内容摘要:

A famous theorem of Artin asserts that the category of discrete G-sets of a topological group G is equivalent to the category of sheaves of sets on a certain orbit category of G equipped with the atomic topology. In this talk I will briefly describe the exact structure of sheaves of sets on $\mathcal{C}$, and give quite a few examples to illustrate the application of this theorem.
