Abelian Yang-Mills theory on a real torus and theta divisors of Klein surfaces

Christian Okonek



Abstract: In joint work with Andrei Teleman we determine certain natural theta line bundles of Klein surfaces as elements in the Grothendieck cohomology group which classifies Real line bundles in the sense of Atiyah. These line bundles are important since they control the orientability of certain moduli spaces in Real gauge theory to a large extend.
