An Introduction to the Seiberg–Witten Equations

Laios Zafeiriou (Bonn) (online)

The Seiberg–Witten equations provide a powerful tool for studying the topology of smooth four-manifolds via gauge-theoretic methods. In this talk, we introduce the equations and the geometric...

Unbounded operator integrals and Quantum Field Theory

Eva-Maria Hekkelman (MPI Bonn)

Operator integrals appear in abundance in many areas of functional analysis. The typical way to deal with these is through a theory called Multiple Operator Integration (MOI). Noncommutative Geometry...

Reflecting isomorphisms of C*-algebras down to groupoids

Jonathan Taylor (University of Potsdam)

It's certainly not true that two étale groupoids with isomorphic C*-algebras are themselves isomorphic (this fails even for finite groups). If however the isomorphism is induced by an appropriate...
