The equivariant cobordism category Journal of Topology (IF1.582), Pub Date : 2021-01-07, DOI: 10.1112/topo.12181 Søren Galatius, Gergely Szűcs
For a finite group , we define an equivariant cobordism category . Objects of the category are ‐dimensional closed smooth ‐manifolds and morphisms are smooth ‐dimensional equivariant cobordisms. We identify the homotopy type of its classifying space (that is, geometric realization of its simplicial nerve) as the fixed points of the infinite loop space of a certain equivariant Thom spectrum.
