16 April 2024: Aaron Kettner, IMCAS and Charles University. Cuntz–Pimsner algebras of twisted partial automorphisms.

This talk will take place in the blue seminar room, back building Žitná 25, and on Zoom.

I will discuss how to construct a -algebra from a vector bundle and a partial action of the integers on the base space of the bundle, using the machinery of Cuntz–Pimsner algebras. This generalizes partial crossed products by the integers, as well as the homeomorphisms twisted by vector bundles recently introduced by Adamo–Archey–Forough–Georgescu–Jeong–Strung–Viola. I will briefly address how to show classifiability of these -algebras.
