"Intro to calibrated geometry"

I will give a brief introduction to the ideas of calibrated geometry, as introduced in 1982 by Harvey-Lawson. In particular I will focus on the Kahler, special Lagrangian, and associative calibrations.

"Q-systems and higher unitary idempotent completion for C*-algebras"

Q-systems were introduced by Longo to study finite index inclusions of infinite von Neumann factors. A Q-system is a unitary version of a Frobenius algebra object in a tensor category or a C* 2-category. By work of Müger, Q-systems give an axiomatization of the standard invariant of a finite index subfactor.

"Quantum Data Compression"

A look at how Shannon entropy and Von Neumann entropy are used to quantify information from classical/quantum sources. In particular Schumacher's quantum source coding theorem will be discussed.
