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...

9th Kálmán Lecture with Ruth Baker: "What is parameter identifiability, why do we need identifiable models, and what can identifiable models tell us about regulation of the cell cycle?"

Ruth Baker (Oxford University)

Ruth Baker from Oxford University will be the speaker of our 9th Kálmán Lecture on Fri 22 May. Ruth will give a one-hour talk after which we can spend some time discussing new DA developments over...
