Vector-valued oscillatory integrals and (ρ, δ)-type pseudodifferential calculus

Gihyun Lee (Potsdam)

I shall report on ongoing joint work with Vishvesh Kumar (Ghent University, Belgium), in which we construct a general pseudodifferential calculus of type \((\rho,\delta)\) associated with symbols...

Cuntz-Pimsner algebras of homeomorphisms twisted by vector bundles

Aaron Kettner (Czech Academy of Sciences)

Abstract:

In this talk, I will show how to construct a C*-correspondence from a
vector bundle together with a (partial) homeomorphism on the bundle's
base space. The associated Cuntz-Pimsner algebras...

How to measure quantum fields? Implementing a causal measurement scheme

Jan Mandrysch (Wien)

While measurement processes in standard quantum mechanics are well understood, the extension of these ideas to quantum field theory (QFT) remains a key challenge. In particular, ensuring that...

Characterizations of p-Parabolicity on Graphs

Florian Fischer

We study p-energy functionals on infinite locally summable graphs for \(p \in (1,\infty) \) and discuss that many well-known characterizations for a parabolic space are also true in this discrete,...
