Equivariant K-theory of compact Lie groups with involution

  • Po Hu, Igor Kriz and Petr Somberg

For a compact simply connected simple Lie group G with an involution α, we compute the G ⋊ ℤ/2-equivariant K-theory of G where G acts by conjugation and ℤ/2 acts either by α or by gα(g)−1. We also give a representation-theoretic interpretation of those groups, as well as of KG(G).
