Song of the Week: Barbara Strozzi - Che si può fare?

Barbara Strozzi (1619-1677) was a prolific composer of secular music - she produced very little sacred music. She also had to navigate a world of men and musical patronage (or lack of it in her case). As the song say, 'What Can One Do'?

German soprano Simone Kermes is the vocalist.

Selflessness for W*-bundles

Max Ryder
((Mathematical Institute University of Oxford))
Abstract

In my talk, I will discuss a new result providing a positive answer to a natural problem about continuous families of projections in II_1-factors. The problem is naturally viewed through the lens of “W*-bundles”, and our proof is via a novel technique which utilises free probability theory in a uniform manner across these bundles. This leads to the notion of selflessness for W*-bundles, which also provides a number of other regularity properties for these objects, such as strict comparison, real rank zero, and stable rank one. This is joint work with David Jekel and Stuart White.
