Speaker
Prof.
Jakob Palmkvist
Description
I will review how the concepts in differential geometry used to describe ordinary gravity can be extended in order to describe supergravity theories, in particular how ordinary diffeomorphisms can be unified with gauge transformations for the additional form fields. I will focus on how Lie superalgebras, in particular tensor hierarchy algebras, can be used even in the restriction to the bosonic sector. The lecture will to large extent be based on collaboration with Martin Cederwall.
