授業の概要
/Course outline
In the basic course, there are two subjects in mathematics: one is linear algebra
and the other is differential and integral calculus. In this class, the basic part
of linear algebra will be taught. Students are required to study this class with
differential and integral calculus, because these subjects are closely
connected each other.
Linear algebra is a field of mathematics that is based on both addition and scalar
multiple, and vectors in high school mathematics are its basic parts. The main
theme of linear algebra is eigenvalue problem that arose from the theory of
simultaneous linear differential equations, while its historical origin is in
solving simultaneous linear equations. The purpose of this class is to learn
necessary notions and techniques to consider eigenvalue problem.
Exercises will be also given side by side with the lectures. Students are expected
to participate subjectively and positively.
Linear algebra has many applications to computer science and engineering. For example,
it is impossible to understand mechanisms of computer graphics without linear algebra.
Further, some fields of mathematics arose from engineering and physics, and developed
under the influences of them. These are the essential reasons why mathematics is
required to learn.

MA01 Linear algebra I
更新日/Last updated on 2023/03/20
授業の概要
/Course outline
Linear algebra II is a continuation of linear algebra I and deals with eigenvalue problem.
Students are required to study this class with differential and integral
calculus because of the same reason that is described in the syllabus of linear algebra I.
For example, matrices and determinants play important roles in differential and integral
calculus of several variables. And eigenvalue problem gives a strong way to solve recurrence
formulae of sequences. Students must know importance of understanding organic connection
between linear algebra and differential and integral calculus. They will also learn bases of
vector analysis that is necessary to learn electromagnetism. Besides, the fundamental policy
does not change from the case of linear algebra I.

(ICTG class starts in Q4.And Prof. Li, P. is in charge of the class.)
Calculus I is devoted to the former half of (differential and integral) calculus. Calculus and linear algebra are essential in the study of mathematical sciences. Since even the vector calculus is needed in the course of physics, the student should get familiar with calculus and linear algebra and understand the relation between them as soon as possible.

Differential and integral calculus started from an understanding of basic objects such as areas of figures and tangent lines to curves, and was based on the Newton's mechanical investigations. Of course, the basic notions in calculus are constructed using that of a limit.

Calculus I deals with calculus of one variable. The basic calculatioal techniques are reviwed and new notions and results are introduced; the rigorous treatment (epsilon definition) of a limit is also (partly) introduced.

Exercises are also offered.

/Course outline
The origin of Fourier analysis goes back to the study of heat transmission (mathematically, "the heat equation") by Joseph Fourier in the early 19th century. Fourier's idea was to “express an arbitrary function using trigonometric functions”. This very school of thought has led to a cornucopia of useful results in applied science, with one major caveat: Whether one can justify the conclusions as Fourier's method dictates has long remained murky, as it hinged on the notion of convergence (limits), which mathematicians in Fourier's time fell short of understanding in rigorous terms (if judged retrospectively by today's standards). Today, mathematically sound mathematical theories are available that underpin the rigor of those applied science fields in which Fourier's theory plays a part. Fourier analysis has earned an enduring status as one of the most important (as in indispensable) and basic mathematical theories. Fourier analysis is a sine qua non not only in studying differential equations, but also in modern applications, e.g., signal processing (including, but not limited to, image information and sound information).

Emphasis will be on practical skills. We may not necessarily dwell too much on mathematical proofs. We thoroughly teach you how to convert a given function into a sum of trigonometric/exponential functions - as a starter. Through solving exercise problems, students will become conversant with calculations and basic theorems of Fourier analysis.

[Competency code]
C-MS-011

Part1. Fourier series expansion
Students will understand what an orthonormal system of the space of functions over finite intervals are. Bessel's inequality.    
Students will understand the notion of Fourier series. Students will learn how to calculate Fourier series for polynomials, exponential/trigonometric functions, etc.

Part2. Properties of Fourier series
Students will learn sufficient conditions for a Fourier series to converge, as well as the relationship between a given function and the Fourier series derived from it. Parseval’s theorem and applications. Weierstrass' theorem.  

Part3. Fourier integral
Students will understand that the notion of Fourier integrals naturally comes to the fore through a heuristic observation, i.e., by way of shifting gears from functions over a finite interval to functions over (-∞, +∞). Students will learn how to calculate Fourier transforms and Fourier inverse transforms of a given function. Some of the more archetypal examples involve an antiderivative of $e^{-x^2})$ and the like. Students will also understand the notion of convolutions (of the functions), as well as the relationship between the convolutions and the Fourier transforms of the functions. Students will learn how to calculate them.

Part4. Laplace transform
Students will understand that Laplace transforms arise as a special case of Fourier transforms. Students will learn how to apply the notion of Laplace transforms to solve a certain type of ordinary differential equations. The case the solution is expressed by a convolution of Laplace transforms will be addressed.

Part5. Discrete Fourier transform
Students will understand that, through some heuristic observation on step functions, paired with a scrupulous use of the theory of Fourier series, one naturally arrives at the theory of discrete Fourier transforms (DFT). Students will understand the similarity between DFT and the theory introduced in Part 2.  Students will also understand that fast Fourier transforms (FFT) are a souped-up version of DFT. Students will appreciate how fast FFTs are.

授業の概要
/Course outline
Although complex functions, in the wider sense, are mappings from complex numbers to themselves, i.e. complex-valued functions of a complex variable, the main objects of Complex Analysis are functions satisfying analyticity. The analyticity is a property of local representability of a function as convergent power series, which is equivalent to the condition that a function is holomorphic (differentiable with respect to a complex variable) in the corresponding domain.

In this course, we introduce complex functions, and learn holomorphy of functions and the Cauchy--Riemann equations. Next we define complex integration along a curve on the complex plane, and learn Cauchy's integral theorem/formula, etc. In virtue of this result, we have the Taylor series expansion and the Laurent series expansion of functions. The former is power series expansion of functions, which is the most fundamental result in Complex Analysis. The latter is applied to the study of singularities and the residue theorem. In addition, we derive many techniques useful for direct applications such as the maximum modulus principle, calculation of solutions to differential equations using the method of power series, and determination of the number of zeros of functions by Rouche's theorem.

When we study Complex Analysis, we are impressed that all of the needed theorems are derived very naturally one after another. Hence it is said that this theory has a beautiful system of mathematics. In particular, the most amazing fact is that every analytic function is completely determined by the behavior in a very small domain. This is similar to the fact that every life can be completely regenerated from a cell.

Analyticity is a property that our familiar many real functions have -- polynomials, rational functions, exponent functions, logarithm functions, trigonometric functions, and all combinations of them have analyticity. Therefore, Complex Analysis is easy to apply to many areas. The knowledge of Complex Analysis is very important for various application areas such as electromagnetism, fluid mechanics, heat transfer, computer system theory, signal processing, etc.

In this course students study properties of sets which have algebraic operations on two elements. According to the condition of operations, the set is called as group, ring and field. Treating abstract algebraic operations derives general properties for these algebraic objects. As fundamentals in computer science students have already studied ``Algorithms and Data Structures''and ``Discrete Systems''. In these courses abstract algorithms, data structures and discrete systems have been introduced and these abstract thinking can be applied to solve many practical problems. These esprits of algebraic systems are the same, and one of basis of the powerful tools to describe, think and solve many practical problems. Using abstract algebraic discussions, coding theory, public key encryption, random number generation and other interesting applications will be introduced. In this lectures proofs of the theorems will be explained simply and the meaning of the theorems and their applications will be enhanced. Furthermore, abstract thinking and deductive thinking will be taught. In order to make students understand the paper exercises and programming exercises will be given. Also quizzes and homework will be carried out to confirm students understanding.

授業の概要
/Course outline
This course consists of logic, deduction of logic, and formalization
of mathematical objects by logic.  This course has four parts as follows:

(i) Review: We first review basic set theory and its related topics
such as binary relations and functions.  We then review Boolean logic.
They are to bring students with different prerequisites to the same
level.


(ii) Basic logics: We introduce two different level logics:
Propositional Logic and First-Order Logic.  Propositional logic is a
classical logic with fundamental operations.  First-order logic is the
fundamental tool to describe many mathematically theoretical
materials.

(iii) Resolution Principle: Resolution Principle is a deduction method
of the first-order logic.  We also study Skolem standard forms,
Herbrand universe, and Herbrand's theorem.

(iv) Logical Formalization of Natural Number Theory: We formalize the
natural number theory under Peano axioms by using first-order logic.

Logic is considered the language of mathematics.  This leads that, in
computer science and engineering, the logic is the foundation and an
important tool.  In this course, we study mathematical logic and also
symbolic logic.  The first objective is to understand both
propositional logic and first-order logic.  The second objective is to
understand the Resolution Principle of propositional logic and
first-order logic.  This is mechanical reasoning.  The third objective
is to formalize a mathematical object by the first-order logic.  To do
so, we, in this course, employ the Natural number theory with Peano
axioms.

授業の概要
/Course outline
The contents of this course include the fundamental concepts on topology, which serves as the foundation of modern mathematics, and its applications.
In topology, also known as "geometry for soft materials," two shapes can be considered as the same if we can transform one to the other smoothly while maintaining the underlying connectivity within the shapes. This idea leads to a new approach to characterizing the global features of shapes and has promoted the development of computer science and engineering so far. Specifically, its contribution ranges from the fundamental representations of graphs and surfaces to the state-of-the-art techniques for extracting features in data analysis. This course will facilitate to study various important concepts for classifying shapes from a topological viewpoint, by employing specific one and two-dimensional shapes as examples.

The objectives of this course are to study several topological invariants or characteristics that describe the global structures of geometric objects, such as the Euler characteristic and the Betti number, together with the topological classification of closed surfaces using their opened ones along boundaries. This will be followed by understanding the relationship between the geometric objects (e.g., the topological space) and algebraic objects (e.g., the Homology group), which allows us to classify the geometric objects by calculating the associated Homology groups.

授業の概要
/Course outline
This course covers a selection of modern applications of geometry and topology to computer science, with particular emphasis on computer graphics and data analysis.

In the first part of the course, we explore some fundamental techniques revolving around the concepts of "Ray Marching" and "Signed-Distance Field", which are standard in both real-time and pre-processed 3D rendering. As an application of these techniques, we learn how to "paint with math" and create high-quality graphics with purely mathematical formulas, using shadertoy.com as our main platform. A sophisticated example is found here: https://www.shadertoy.com/view/ld3Gz2

In the second part of the course, we cover an emerging technique in topological data analysis called "Persistent Homology". This technique extracts information from a data set by viewing it as an approximation of a topological space and studying its topological properties that remain persistent across several levels of approximation. We begin by reviewing homology's basic definitions and properties, then delve into algorithms for calculating homology groups of simplicial complexes. As a practical application, we construct a simple software tool to perform Persistent Homology on reasonably sized datasets.

成績評価の方法・基準
/Grading method/criteria
Each student can choose between two options:

Option 1: Programming project. The student will implement an original shader on shadertoy.com by utilizing the theory learned in the course and combining it with features found in other shaders. The student should be able to explain the purpose of each line of code in his/her project. Each project is individual; it can be started at any time during the course and has to be completed by the end of the term.

Option 2: Written exam. In a classroom setting, the student will answer written comprehension questions about the theories discussed in the course. Additionally, there will be exercises to test the student's practical understanding of the concepts learned.
履修上の留意点
/Note for course registration
Students are expected to have a working knowledge of at least one programming language, simple data structures, discrete mathematics, and basic linear algebra. Some familiarity with computer graphics, elementary group theory, basic topology and homology is preferred but not required.
