Abstract

“Stuff happens” in characteric p, creating a more challenging context for algebraic geometers and representation theorists than the classical context of working over the real or complex field. Algebraic groups are the algebraic formulation of Lie groups, and their representations are perhaps the most relevant and least accessible. Even the category of representations of Z/p x Z/p on finite dimensional k-vector spaces is “unclassifiable”. Examples are key to suggesting general patterns. We describe constructions in algebraic geometry which contribute to our understanding of modular representations of algebraic groups as “elementary” as the additive group G_a or as “simple” as the special linear group SL_n.
