| Abstract: |
|---|
| Let G be a compact Lie group and T be its maximal torus. Let A,B be G-C^\ast-
algebras. We define certain divided difference operators on the T-equivariant
KK-group KK_T(A,B). The main result is that a T-equivariant KK-class is G-
equivariant iff it is annihilated by an ideal generated by these divided
difference operators. Its relations to the Weyl's character formula and
symplectic geometry will also be given. |
