Chevalley's restriction theorem for reductive symmetric superpairs

Alexander Alldridge, Joachim Hilgert, Martin R. Zirnbauer

Let (g,k) be a reductive symmetric superpair of even type, i.e. so that there exists an even Cartan subspace a in p. The restriction map S(p^*)^k->S(a^*)^W where W=W(g_0:a) is the…
