Course overview and goals
The objective of this course is to explain the fundamentals of set theory and topology. The main theme of this cousrse is set theory. In the first half of this course, lectures on sets, maps, axiom of chice, equivalence relations, and the cardinarity of sets are given. In the the last half of this course, orderd set, Zorn's lemma, and the topological properties of metric spaces are given. This course is aimed to connected to the course "Set and Topology II" in the third quarter.
Course description and aims
(Theme)
The set and topology play an important role in mathematical and computing science. The objective of this course is to explain the fundamentals of set theory,
and topological properties of metric spaces as an introduction of topology.
(The goal)
The students are expected to understand the fundamentals of mathematical methods to handle the concept of sets, maps, and metric spaces appeared in mathematical and computing science and also to be able to apply them to practical problems.
Keywords
set, mapping, family of sets indexed by a set, the axiom of choice, equivalence relations, quotient set, cardinality of sets, countabe set, uncountable set, order, linearly ordered set, Zorn's lemma, Euclidean space, metric space.
Competencies
- Specialist skills
- Intercultural skills
- Communication skills
- Critical thinking skills
- Practical and/or problem-solving skills
Class flow
The lectures will provide on zoom the fundamentals of set theory and an introduction of topology of metric spaces. Of the two lectures per week, one is live and once is recorded on-demand. Live lessons will also be recorded and URLs will be distributed. We will give feedback and quizzes by Google form every time, and follow up in the next class.
The students are strongly encouraged to register for "MCS.T202：Exercises in Set and Topology I" simultaneously which offers the recitation session for this course.

Study advice (preparation and review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Textbook(s)
"Set and Topological Space (in Japanese)" by Shigeyuki Morita published by Aasakura Shoten.
Reference books, course materials, etc.
The lecture notes will be available online.
Evaluation methods and criteria
Evaluation will be made by quizzes and reports. In the quiz, the basic understanding of the lecture content will be asked, and the report will consist of the questions to be considered.
