Outline (in English)

(Course outline)
This class is on number theory. The goals are: 1) to learn basic properties of integers, which are usually taught as "elementary number theory," and 2) to learn definitions and properties of Gaussian integers and the ring of polynomials, which are usually taught as the generalization of elementary number theory. We improve our skills on how to apply mathematical abstract concepts to concrete contents. Also, as an application of elementary number theory to engineering (information security) we learn RSA encryption algorithm.

(Specific goals)
In the first half of the course, from the perspective of elementary number theory, we learn multiples, divisors, Euclidean algorithm, linear Diophantine equations, integer factorization, congruence and remainders, linear congruence equations, Euler's theorem, Fermat's little theorem, and application to RSA encryption.
In the second half, we learn an introduction to abstract algebra, forcusing on commutative rings such as the ring of Gaussian integers and that of polynomials as the generalization of elementary number theory.

(Work to be done outside class)
One should expect about 4 hours for preparation for the next class and review of the previous one. Please review throughly and understand fully the contents of previous lectures. When considering appropriate, we shall carry out assignments (which we call "small reports") consisting of exercises. Please submit your reports (papers) by the next class. Depending on the achievement of the class, if needed, we may carry out additional reports (optional) focusing on more applied (advanced) problems. In addition, if necessary, we may carry out a final report (again, optional) consisting of applied problems.

(Grading criteria/policy)
Pass / fail shall be determined based on the scores of the small reports (50%) and the score of the final exam (50%). The additional and final reports, which may be conducted as needed, shall be added to the scores of those who have passed, within the ranges that do not exceed the full marks of the small reports and the final exam.
