Abstract: | Decomposition numbers encapsulate the relationship between ordinary and modular representations of finite groups. Determining decomposition matrices is a difficult problem, particularly for the finite groups of Lie type in non-defining characteristic. I will present some recent developments which allow us to consider tackling this problem for the quasi-isolated blocks of finite groups of Lie type in non-defining characteristic, and discuss some of the strategies and challenges involved in this project.
