Basic sets for blocks of finite groups of Lie type
Let G be a finite group and let B be a p-block of G with p a prime. Roughly speaking, a basic set for B relates the irreducible modular and irreducible ordinary characters in B in a very useful way.
When G is a finite group of Lie type, Geck and Hiss gave a non-constructive proof of the exsistence of basic sets for all p-blocks of G under some mild conditions on the prime p. In my talk I will explain how to construct these basic sets explicitly for certain groups of Lie type under similar conditions on the prime p.
