Topology Seminar: Daniel Sheinbaum

We will attempt, in a colloquium-like fashion, to introduce the basic concepts of quantum mechanics and functional analysis necessary to derive the connection between twisted equivariant K-theory of a d-1 dimensional torus and quasi-adiabatic stability of Fermi surfaces of non-interacting fermions on a crystalline half-solid with a gapped bulk condition. This is part of the speaker's PhD thesis and is an extension of joint work with A.Adem, O.A. Camarena and G.W. Semenoff.
