Topology Seminar: Cihan Okay
Topic
Spherical posets from commuting elements
Speakers
Details
Given a group G the space of n-tuples of pairwise commuting elements can be assembled into a subspace Bcom(G) of the classifying space BG. This space classifies certain types of principal bundles, but unlike BG it is not always aspherical for discrete groups.
The universal cover can be studied using posets, and when G is an extraspecial p-group, I will show that it has the homotopy type of a wedge of spheres. Extraspecial groups appear as the basic observables in quantum computation, and I will also talk about some recent applications of Bcom(G).
