Pure Maths Colloquium: Noncommutative manifolds

Presented by Nicholas Young , Newcastle

30 April 2018 16:00 in CM221

Analytic functions of non-commuting variables are defined by abstraction from the properties of polynomial functions of tuples of matrices. Their theory has been much developed over the last decade, under the title of `free analysis' or `noncommutative analysis'.

I will describe the construction of the free Riemann surface of the matricial square root function. For this purpose one has to introduce the notion of a noncommutative manifold.

This is joint work with Jim Agler (UCSD).
