Cohomology of the classifying spaces of $U(n)$-gauge groups over the 2-sphere
Published 13 Aug 2019 in math.AT | (1908.04448v1)
Abstract: A gauge group is the topological group of automorphisms of a principal bundle. We compute the integral cohomology ring of the classifying spaces of gauge groups of principal U(n)-bundles over the 2-sphere by generalizing the operation for free loop spaces, called the free double suspension.
