Let G be an algebraic group defined over a finite field. One of the goals of the theory of character sheaves is to understand the irreducible characters of the groups of rational points of G, in terms  of  certain geometric objects on G. To begin with, I will describe some of the goals of the theory of character sheaves and the tools used like Grothendieck's sheaf-function correspondence. Then I will discuss some ideas from representation theory of finite and nilpotent groups which serve as a motivation to theory of character sheaves on unipotent groups initiated by Drinfeld.
