Abstract:  In this talk, we briefly introduce the torus equivariant elliptic cohomology, which is a sheaf over (products of) complex elliptic curve. We also discuss Thom isomorphisms in this context. Then we show the existence of global sections of Thom spaces with respect to sigma orientations. Finally, we relate these to the rigidity problem of Witten.
