Course description and aims
The main subject of this course is basic concepts in set theory. After introducing some fundamental operations for sets such as intersection, union and complement, we explain basic notions for maps between sets, such as injection, surjection, and bijection. Next we introduce binary relations on sets, especially the concept of equivalence relation and the associated quotient set. Finally, we introduce the equivalence of sets, and learn the notion of cardinality. Each lecture will be accompanied by a problem solving class. This course will be succeeded by “Introduction to Topology II” in the second quarter.
The notions of set and map are fundamental not only in mathematics but also in science, and are applicable to describe a wide variety of objects. On the other hand, these abstract notions are not easy to comprehend without suitable training. To that end, rigorous proofs will be provided for most propositions, lemmas and theorems.
