Vinberg theory, which describes invariant theory for representations coming from certain graded Lie algebras, is well understood except over fields of very small characteristic. I will talk about results related to the property of stability in these representations: in these examples, we can describe stable vectors in a uniform way that is independent of the field of definition. These results are motivated by a construction of representations of p-adic groups by Reeder—Yu, and if time permits I will talk about this motivation.
