First steps towards an equivariant Lorentzian index theorem

String geometry is to string theory what spin geometry is to gauge theory. String geometry can be studied via infinite-dimensional geometry and representation theory on loop spaces, or by higher-categorical geometry and representation theory on manifolds. In this talk I will give a gentle introduction to these topics. A central strategy in the field is to join the forces of loop space geometry and of higher-categorical geometry, and I will try to explain some basic machinery in this context. At the end I will describe some recent results about the so-called "stringor bundle". This is joint work with Peter Kristel and Matthias Ludewig.
Forthcoming speakers are Lashi Bandara on June 18th, Florian Hanisch on June 25th, Bernadette Lessel on July 2nd, Ihsane Malass on July 9th, Diego López on July 16th and Larisa Jonke on July 23rd
