Title: When is complete reducibility inherited?
Abstract: A subgroup X of G = GL(V) is said to be G-cr if X acts completely reducibly on V. In the 1990s, Serre generalized this to subgroups of an arbitrary connected reductive algebraic group G, a concept that has generated a lot of interest since. I will present joint work with Martin Liebeck (Imperial) and Alastair Litterick (Essex) on the following fundamental questions: Let X < H < G with X and H connected. Does X being H-cr imply it is G-cr? Does X being G-cr imply it is H-cr?
