Abstract

We extend McClure's results on the restriction maps in equivariant KK-theory to bivariant KK-theory: Let GG be a compact Lie group and AA and BB be GG-CC^*-algebras. Suppose that KKnH(A,B)KK^{H}_{n}(A, B) is a finitely generated R(G)R(G)-module for every HGH \le G closed and nZn \in \Z. Then, if KKF(A,B)=0KK^{F}_{*}(A, B) = 0 for all FGF \le G {\em finite cyclic}, then KKG(A,B)=0KK^{G}_{*}(A, B) = 0.
