Heat and resolvent expansions in the noncommutative case

Matthias Lesch (Bonn)

Heat and resolvent expansions are a fundamental tool in spectral geometry and index theory. In the noncommutative world (á la Connes) such expansions exhibit fundamentally new structures. I will...

On factoriality of the Neretin group von Neumann algebra

Basile Morando (ENS Lyon)

To any locally compact group G, one can associate a von Neumann algebra L(G), generated by the image of G under its left regular representation. This algebra reflects decomposition properties of the...

Cancellation properties of exotic 4-dimensional positive scalar curvature metrics

Johannes Ebert (Münster)

It is well-known that 4-dimensional smooth topology offers many exotic phenomena, typically detected by means of gauge theory, and it is also well-known
that these exoticities are very unstable when...
