Abstract

We compute the additive structure of the Hermitian KK-theory spectrum of an even-dimensional Grassmannian over a base field kk of characteristic zero in terms of the Hermitian KK-theory of XX, using certain symmetries on Young diagrams. The result is a direct sum of copies of the KK-theory of the base field and copies of the GWGW-theory of the base field, indexed by \emph{asymmetric} and \emph{symmetric} Young diagrams, respectively.
