Äquivariante whiteheadtorsion

  • Henning Hauschild


In this note we compute the equivariant Whiteheadgroups WHG(X) introduced by S. Illman. Because a G-homotopy equivalence is in general not isovariant, and a G-diffeomorphism is isovariant, the group WhG(X) does not give the right invariants for the equivariant s-cobordism theorem. So we introduce the isovariant Whiteheadgroup IWhG(X), prove an isovariant s-cobordism theorem and give some applications.
