Additionally, we give spectral sequences for computing the homotopy groups of the unitary deformation K-theory of a group G and the cofiber of the Bott map in terms of PU(n)-equivariant K-theory and homology of spaces of G-representations.36 pages (revised version)K-Theory and HomologyAlgebraic TopologyRepresentation Theory19D23 (Primary) 19L41, 20C99 (Secondary)The product formula in unitary deformation K-theorytext
