We put two C*-algebras together in a noncommutative tensor product using quantum group actions on them and a bicharacter relating the two quantum groups that act.
We will discuss a technique which allows one to approximate singular varieties by smooth spaces called stacks. As an application, we will address the following question, as well as some generalizations: given a linear action of a group G on complex n-space C^n, when is the quotient C^n/G a singular variety? We will also mention some applications to Hodge theory and to derived equivalences.
In this talk, I will begin to tackle the last two pages of the proof of the bounded width conjecture. It will likely take two lectures.
“Semisimple Lie Algebras”
In my talk I present results from the joint paper [1]. We prove that the intersection G ∩ A of an infinite geometric progression
The corona theorem is a celebrated result about maximal ideals of the algebra of all bounded analytic functions on the unit disc.
We put two C*-algebras together in a noncommutative tensor product using quantum group actions on them and a bicharacter relating the two quantum groups that act.
Let F be a field, G a group and V a finite dimensional representation of G defined over F.
Abstract: See title.
Root spaces are a generalization of eigenspaces, and it turns out that a semisimple Lie algebra can be recovered by its roots.
