Trace is a fundamental concept in representation theory. The importance of its categorical analogue is only realized in recent years. In this talk, I will introduce this notion and explain why some familiar construction in representation theory (Springer theory, Deligne-Lusztig theory) and in algebraic geometry are related to this notion.
