Marzieh Forough. Lifting problem for completely positive maps.
This talk will take place in the blue seminar room, back building Žitná 25, and on Zoom.
I will explain the lifting problem for completely positive maps between C*-algebras carrying continuous actions of locally compact Hausdorff groupoids, extending our earlier results for locally compact Hausdorff groups. For this, I need to describe the properties of Busby invariants of equivariant extension of G-algebras where G is a locally compact Hausdorff groupoid.
Based on ongoing work with Suvrajit Bhattacharjee (extending my previous work with Eusebio Gardella and Klaus Thomsen).
