Geometric versus homotopy theoretic equivariant bordism
By results of Loeffler and Comezana, the Pontrjagin-Thom map from geometric
G-equivariant bordism to homotopy theoretic equivariant bordism is injective
for compact abelian G. If G = S^1 x ... x S^1, we prove that the associated
fixed point square is a pull back square, thus confirming a recent conjecture
of D. Sinha. This is used in order to determine the image of the
Pontrjagin-Thom map for toral G.Comment: 19 pages, minor inaccuracies removed, to appear in Math. An
