The models of computations will be introduced and the term rewriting
systems (TRS), as a universal model of computation, and its major
properties such as termination and confluence will be discussed. Term
rewriting is a branch of theoretical computer science which combines
elements of logic, universal algebra, automated theorem proving and
functional programming. Its foundation is equational logic. TRS
constitutes a Turing- complete computational model which is very close
to functional programming. It has applications in Algebra, recursion
theory, software engineering and programming languages. In general
TRSs apply in any context where efficient methods for reasoning with
equations are required.

Course implementation methods: Combination of face-to-face classes and remote classes

In this class, we deal with various topics arising from pure and applied mathematics concerning Algebraic Systems and Combinatorics. This year, we focus mainly on the theory of finite fields in the area of Algebraic Systems. The finite field F_q --- a field with finite (q) elements --- was first found by E. Galois, and so it is often called a Galois field GF(q). The structure of F_q as a field is uniquely determined by the number of elements q, and for the existence of F_q, it is necessary and sufficient for q to be a power of a prime p.

Beginning with polynomial rings, we overview the following: prime fields, finite polynomial fields, field extensions, splitting fields, structure of finite fields, primitive elements, Frobenius cycles, cyclotomic polynomials, and functions between finite fields. When we consider numbers, they are often supposed to be real or complex numbers. But here, we shall contact with more abstract numbers, rings, and fields, to develop the ability of mathematical and abstract thinking.

Finite fields are purely mathematical objects. For example, mathematicians often try to extend or modify the theory over real/complex numbers to the one over finite fields in their researches. Finite fields, however, have many application such as theory of experimental design, codes, and logical circuits, etc, which is the reason why the finite fields are very important objects for both of Scientists and Engineers.

授業の概要
/Course outline
This is a unique course co-taught by a cryptographer and a pure-mathematician. Kachi (mathematician) teaches the first half and Su (cryptographer) teaches the second half.

From the mathematical side we cherry-pick topics that give a good account of themselves within pure-math (commensurate in quality to rival graduate schools’ math programs), with an eye towards its application to post-quantum cryptography. Jacobi sums proved to have applications in primality testing of large integers (à la Adleman–Pomerance–Rumely). The latter is of immense importance in RSA, albeit it is a ‘pre’-quantum public key algorithm. We are naturally prompted to recalibrate the theory of Jacobi sums in hope it might potentially yield an algorithm of cryptographic significance specifically in the ‘post’-quantum context. In that spirit we cover the theory of sums of roots of unity (Gauss sums, Jacobi sums), incorporating the ideas from discrete Fourier analysis.

From the cryptography side we gear the course towards post-quantum cryptography: Brief introduction to cryptography (encryption, security, public key cryptography, computational complexity); introduction to post-quantum cryptography; q-linear-code-based encryption scheme; multivariate quadratic cryptosystem; lattice-based cryptosystem; isogeny-based cryptography, and quantum Fourier analysis.
授業の目的と到達目標
/Objectives and attainment
goals
1. Understand that math and cryptography are two scholarly disciplines that set themselves apart in that they are both purely theoretical, and deductive-reasoning-based. Understand that cryptography employs the principles of pure-math in the most fundamental way.
2. Understand the basics of roots of unity and their sums. Understand the invariant theory-incorporated framework. 3. Understand the raison d’être of post-quantum cryptography (i.e., the advent of quantum computers). 4. Understand the basics of post-quantum cryptography, and know what’s at stake in the cutting-edge level cryptography research field.

授業の概要
/Course outline
Signal processing is one of the fundamental theories and techniques for constructing modern information systems.  During the last half century, many theories and methods have been proposed and widely studied for signal processing. In this core course, first, we review the fundamentals of discrete-time signals and systems. The related content includes the concept and the classification of discrete-time signal, representations of signals in time, frequency, z- and discrete frequency domains, representations and analyses of systems, and filter designs. Then we focus more on stochastic signals/systems, besides of deterministic signals/systems, which is the main topic of the undergraduate course “Signal Processing and Linear System”. Topics include estimation theory, random signal modeling, characterization of stochastic signals and systems, nonparametric estimation, adaptive signal processing, and Kalman filtering.

Computation is one of the most important concepts in computer science, and indicates the limit of the power of computers, which should be familiar to all people working in computer science or engineering field.
By this notion, the problems are classified into two classes, that is, the class consisting computable or solvable problems and one consisting incomputable or unsolvable problems.
This course provides the notion of computation and computability through several computation models as the rigorous concepts of computation and their equivalence, and the existence of non-computable problems and some concrete examples of non-computable problems.
授業の目的と到達目標
/Objectives and attainment
goals
Students can be familiar to the notion of computability defined by several computation models, such as Turing machines, register machines, recursive functions and While programs. Furthermore, they can understand the limit of the computers, that is, that there are problems which are not solved by any computer.

Artificial intelligence (under graduate course)
更新日/Last updated on 2022/01/25
授業の概要
/Course outline
Most (if not all) engineering problems can be formulated as optimization problems. To solve optimization problems, different methods have been studied in mathematical programming, operations research, and so on. Conventional methods, however, are usually not efficient enough when the problem space is large and complex. Many problems faced in artificial intelligence are combinatorial optimization problems. These problems are NP-hard, and we may never find polynomial time solutions. To solve these problems efficiently, different "heuristics" have been used to "search for sub-optimal solutions".

Heuristics are search methods produced based on human intuition and creative thinking, and are often useful for finding good local solutions quickly in a restricted area. Meta-heuristics are multi-level heuristics that can control the whole process of search, so that global optimal solutions can be obtained systematically and efficiently. Although meta-heuristics cannot always guarantee to obtain the true global optimal solution, they can provide very good results for many practical problems. Usually, meta-heuristics can enhance the computing power of a computer system greatly without increasing the hardware cost.

So far many meta-heuristics have been proposed in the literature. In this course, we classify meta-heuristics into two categories. The first one is "single-point" (SP) search, and the second one is "multi-point" (MP) search. For the former, we study tabu search, simulated annealing, iterated local search, and so on. For the latter, we study evolutionary algorithms, including genetic algorithms, genetic programming, evolutionary strategy, and memetic algorithm; ant colony optimization, and particle swarm optimization. Although the efficiency and efficacy of these methods have been proved through experiments, because they were proposed based on human intuition, the theoretic foundation is still weak. Therefore, in this course, we will mainly introduce the basic idea of each method, and try to explain the physical meaning clearly. Mathematical proofs will be introduced very briefly when necessary.

/Note for course registration
This course is related to "optimization" or "search". If you are interested in knowing how to find (search for) the "best" solution for any given problems, effciently and effectively, please take this course. Note that designing deep neural networks, electronic devices, and so on, are all "special cases" of optimization problems.

Course implementation methods: Remote classes

A graph, composed of vertices and edges, is one of the most fundamental objects in mathematics. In spite of its simple definition, tons of notions concerning graphs are introduced, and it is sometimes very laborious to perform complete introduction of graph theory. In this class, we first overview graph theory terminology to moderate extent, then we change the focus to carefully selected important topics, and advance our knowledge in that area. For example, we focus on vertex/edge connectivity, and introduce Menger's theorem and Mader's theorem; also focus on spanning trees and Kirchhoff's theorem, etc.

Graph theory, as a branch of mathematics, growing its branches like a tree, and even at present, contains many difficult open problems. As another aspect, it has a lot of applications to several areas. Graphs can be used to model many types of relations and processes in physical, biological, social and information systems. This is a reason why graph theory is important for many people in wide areas.
