Abstract:
This paper mainly deals with the question of equivalence between
equivariant cohomology Chern numbers and equivariant $K$-theoretic
Chern numbers when the transformation group is a torus. By using the
equivariant Riemann-Roch relation of Atiyah-Hirzebruch type, it is
proved that the vanishing of equivariant cohomology Chern numbers
is equivalent to the vanishing of equivariant $K$-theoretic Chern
numbers.
