摘要(Abstract):

In this seminar, we mainly study the Category Theory, which contains functors, natural transformations, the Yoneda lemma, (co)limits and adjoint functors. The aim of this seminar is to introduce the language, philosophy, and basic theorems of Category Theory. The study of category is to try to grasp the common characteristics in various related "mathematical structures" by means of "axiomatic" method, and to correlate these structures by means of "structure preserving function" between structures. Therefore, we can get better to learn other knowledge related to algebras through this systematic study of category theory.
