授業の概要 ／Course outline |
(ICTG class starts in Q3.And Prof. Asai and Prof. Cong-Thang Truong is in charge of the class.) 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. |

(ICTG class starts in Q1.And Prof. Schmitt is in charge of the class.) 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. |
授業の目的と到達目標 ／Objectives and attainment goals |

授業の概要 ／Course outline |
(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. |
授業の目的と到達目標 ／Objectives and attainment goals |
Establishing the foundation of the basic calculational techniques studied in high school, we introduce advanced notions and results such as inverse trigonometric functions, expansion of a function, and recurrence relation of integrals. Calculus I is foundation for an understanding of Calculus II, Probability and Statistics, Fourier analysis, Complex function theory, Physics, and all fields of computer sciences. |

(ICTG class starts in Q3.And Prof. Li, X. is in charge of the class.) The origin of Fourier analysis is a study of the heat equation (differential equation) by Fourier in early 19th century. The basic idea was “express arbitrary functions by using trigonometric functions well!” This way of thinking led to many useful results in many application fields, but it was uncertain whether the conclusions were mathematically justified, since the concept of convergence had not been discovered. In the present day, a proper theory has been developed for conventional sciences and technologies. Fourier analysis is an indispensable basic theory for not only processing differential equations of Fourier’s era, but also modern applications, e.g., signal processing (including for image information and sound information, etc.) The technique for handling the given function by using trigonometric functions and exponential functions is given though we will not examine of mathematical proofs in this lecture. Through the answers to the exercises, students will become familiar with calculations and skilled at using basic theorems of Fourier analysis. |
授業の目的と到達目標 ／Objectives and attainment goals |
Part1. Fourier series expansion Students will understand the orthonormal system of the space of the functions defined over finite intervals and Bessel's inequality. Students will understand the Fourier series of trigonometric functions and will calculate them for the functions expressed by polynomials, exponential functions or trigonometric functions. Part2. Properties of Fourier series Students will understand conditions of convergence of Fourier series, the relationship between a given function and the Fourier series derived from it. They will understand Parseval’s theorem and apply it. They will also understand Weierstrass' theorem. Part3. Fourier integral Students will understand that the Fourier integral is obtained through a heuristic method that extends finite intervals to infinite ones and calculates Fourier transforms and Fourier integrals (Fourier inverse transforms) of given functions. Target functions are not only elementary functions described above, but also the functions of the type $e^{-x^2})$. They will also understand a convolution of the functions, the relationship between the convolutions and the Fourier transforms of the functions and calculate them Part4. Laplace transform Students will understand the Laplace transform as a transform based on Fourier transform and apply it to solving a certain kind of ordinary differential equations. The method by which the solution is expressed by a convolution of the Laplace transform is included. Part5. Discrete Fourier transform Through the heuristic consideration of the stepping functions by applying the theory of Fourier series, students will understand the theory of discrete Fourier transform (DFT) similar to the theory introduced in Part 2. They will also understand the method of the fast Fourier transform (FFT) as an efficient algorithm of DFT and appreciate its speed. |

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. |

The course has three parts: (1) Review of Boolean Logic and Propositional Logic. ============================================= Review to bring students with different prerequisites to the same level. Topics discussed include: Mathematical propositions and propositional logic (truth values in {0,1}); Set theory; Boolean algebras as generalizing principle of the latter two subjects; Stone's Theorem. Some computer applications of the material is discussed as well. (2) Fuzzy Sets and Applications. =========================== Here the structure of (1) is generalized to truth values in the full interval [0,1] in IR. This allows to define fuzzy subsets of a given set, the embedding of regular sets into the set of fuzzy subsets. A special case of fuzzy subsets are fuzzy relations. The main application of this chapter is the rigorous development of the Tamura classification method based upon a given fuzzy relation. An indication how to use this method in image reconstruction is given. See: http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=5408605 (3) Model Theory. ================= In mathematics, model theory is the study of (classes of) mathematical structures (e.g., groups, fields, graphs, universes of set theory) using tools from mathematical logic. A theory is built which allows to say in a proper calculus: One can verify a formula or theorem in any set interpretation, if and only if one can find a formal proof of that formula or theorem by means of strict textual manipulations according to a fixed set of proof-rules without referring to special properties of any example. This is known as Goedel's completeness theorem. |

授業の概要 ／Course outline |
We study the ideas of topology from the application perspective of analysis. For this purpose, the definition of the real numbers IR is reviewed and it is shown how the sup-axiom in IR relates to the existence of limits. In the major part of the course, the relationship between (1) limits in IR^n (2) the canonical topology in IR^n (3) continuous functions is discussed. The relationship between these structures is studied extensively. As an application, we show, e.g., that compactness and associated uniform continuity are the ingredients which make integration work. The second major part of this course introduces a rigorous treatment of the concept of continuous deformation (homotopy) and the fundamental groups which one can construct using homotopy equivalence classes of continuous functions on a set with a given topology. As an application we show the fundamental theorem of algebra at the end of the course. |
授業の目的と到達目標 ／Objectives and attainment goals |
Learn topological concepts in the context of the geometry in finite dimensional vector spaces and the natural (Euclidean) norm including embedded objects such as the torus in IR^3. Relate the concepts of supremum, limit, topology and continuous functions. Show how these concepts and homotopy apply in other mathematical disciplines. |
