"Markovianity and the Thompson Monoid F+"

We show that representations of the Thompson monoid F+ yield a large class of unilateral stationary noncommutative Markov processes. As a partial converse, unilateral stationary Markov processes in tensor dilation form (and in particular, in the commutative setting) are shown to yield representations of F+. This is joint work with Claus Koestler and Stephen J. Wills.

"Haagerup's noncommutative Grothendieck inequality (cont. cont.)"

We will continue^2 to prove things related to and on the subject of the NCG theorem. Possibly we will finish the proof of the theorem this week, and possibly not; we conjecture that no third option exists, but we are unable to prove this claim at present. Time permitting, we may attempt to prove this rigorously; this attempt is unlikely to be successful, veracity of the claim notwithstanding.

"GIT Quotients, Part II"

I will continue my previous talk on GIT quotients. I will focus on projective GIT quotients and then discuss the Kempf-Ness theorem, which relates the symplectic reduction of smooth complex projective varieties to GIT quotients.

"Reverse Math - VI"

In this talk, we will be presenting material from a recent book by Damir Dzhafarov and Carl Mummert. In particular, we will begin Chapter 5, studying subsystems of second order arithmetic.

"Detecting certain properties of C*-algebras"

A C*-algebra $A$ is said to detect a certain property $\mathcal{P}$ (or is a $\mathcal{P}$-detector) if, for any C*-algebra $B$, we have $A\otimes_{\min}B=A\otimes_{\max}B$ is and only if $B$ has property $\mathcal{P}$.  In this talk we will survey several properties that can be detected, as well as present the algebras which play the detector's part.

"Properties of Schemes"

We will talk about some properties of schemes, including possibly integral, separated, and proper, if time permits.
