Noncommutative Geometry

Speaker: Ali Fathi (Western University)

"Canonical trace and spectral invariants of noncommutative tori"

Time: 15:00

Room: MC 107

I will explain some of our new results on spectral eta invariant of certain families of Dirac operators on NC tori.

"Inclusions Among Mixed-Norm Lp Spaces"

Time: 13:30

Room: MC 107

Mixed norm Lebesque spaces are Banach spaces of multi-variable functions for which a different Lp norm is used in each variable. In many cases, there are simple, easy-to-compute conditions that ensure one given mixed norm space is contained in another. In other cases, only complicated, hard-to-compute conditions will do.

Noncommutative Geometry

"Introduction to cyclic cohomology and its applications II"

Time: 11:00

Room: MC 106

In these series of lectures I shall cover some of the main ideas and results in cyclic cohomology and its application to problems in index theory.

"Recent results on optimal Hardy's inequalities and isometric averaging operators"

Time: 15:30

Room: MC 107

Classical Hardy's inequalities have been recently considered in a more general context than Lebesgue spaces (e.g., monotone functions, weighted inequalities, Hardy operator minus the identity, etc.) I will present some of the main results obtained in these new settings, as well as an extension to discrete averaging isometries.
