Colloquium: Anna Skripka UNM, Untangling noncommutativity with operator integrals
Event Description:
Untangling noncommutativity with operator integrals.
Abstract: Operator integration is a collection of powerful methods and techniques that enable analysis of functions with noncommuting arguments. Such functions arise, in particular, in various problems of matrix analysis, mathematical physics, noncommutative geometry, and statistical estimation. Theory underlying multilinear operator integration has been developing for some seventy years, and by now has accumulated many deep results and important applications. I will give a flavor of the subject and present several recent advancements in differentiation and approximation of operator functions.
