Relating the integrated density of states to spectral flow in aperiodic chains.

Johannes Kellendonk (Lyon)

Abstract: Aperiodic insulators have typically richer topological invariants than periodic ones. 

In particular the gap labelling group has more generators. We ask, how we can “measure” the gap labels...

Causal inference: A very short intro

Jakob Runge, University of Potsdam

Machine learning excels in learning associations and patterns from data and is increasingly adopted in natural-, life- and social sciences, as well as engineering. However, many relevant research...

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...
