14:00 MCS2068 S&MJenny Pi (Oxford): Classifying (some) non-amenable C*-algebras

In the 2000s, Dykema and Radulescu proved that any infinite free product of amenable diffuse type II_1 factors is isomorphic to the von Neumann algebra of the free group with infinitely many generators. We discuss some work-in-progress on a C*-analogue of this fact. We obtain an interesting application to C*-superrigidity of groups. This is based on joint work-in-progress with Jakub Curda, Shanshan Hua, Gregory Patchell, Austin Shiner, and Stuart White, and inspired by recent work of Hirshberg and Phillips.

11:00 MCS2050 E&PJohn Hunton (Durham): Please Sir, can we have some Moore?

RH Moore developed his method of teaching mathematics in the US, in the early part of the 20th century. It lives on in many places, with varying degrees of fidelity to the original ideas and versions of it are often referred to as Inquiry Based Learning (IBL). I first came across it when, working at the University of Leicester, a colleague joined us who had experience teaching a Moore Method course in Alabama. Together we concocted a second year module that while based on the Moore Method, was also adapted to fit the UK system, and moreover was suitable to teaching to an entire year group. The Leicester module then informed the second term content of the then new Durham Discrete Maths module, when I moved here. This talk will be part historical, part discussion of my experiences and observations, of the pros and cons of the Method and its adaptations, and hopefully will lead to some discussion of the topic with those present. One question that interests me is whether there is either scope or appetite for more IBL in the future Durham syllabus.
