**Lecture 1 (5/30)**: *Algebraic representations *

This will be an introduction to the theory of algebraic representations. I will discuss the representation theory of SL_2, and general reductive algebraic groups, recalling the fundamental Steinberg tensor product and restriction theorems. I will then turn to Lusztig's character formula and its status.

**Lecture 2 (5/31)**: *Constructible sheaves *

I will discuss the geometric Satake equivalence and Finkelberg-Mirkovic conjecture. This provides a conceptually satisfying setting in which to understand Lusztig's conjecture. Understand Lusztig's conjecture for a fixed prime leads to subtle questions concerning torsion in intersection cohomology. I will discuss what is known and what remains to be understood.

**Lecture 3 (6/1): ***Higher representation theory*

I will discuss the Hecke category in its constructible and diagrammatic incarnations, and state recent theorems and conjectures which suggest that the Hecke category completely controls algebraic representations (as a "module category" in the sense of higher representation theory). Finally, I will try to motivate a recent conjecture with Lusztig.
