Stratified learning, cell biophysics, and material structures

Abstract

Geometry and topology call tell us about the shape of data. In this talk, I will give an introduction to my work on learning stratified spaces from samples, look at the use of persistent homology in cell biophysics, and apply persistence in understanding material structures.

Exploring the $c$ - the conformal anomaly and spaces of field theories

Ludovic Fraser-Taliente
Abstract
$c$ is pretty cool. In two-dimensional critical theories, we are surrounded by it: it appears in the Virasoro central charge, the Stefan-Boltzmann constant, the conformal 'anomaly', the entanglement entropy, and at the endpoints of the Zamolodchikov $C$-function - and, of course, it doesn't appear on the string worldsheet. I will explain these appearances and the tight relationships between them, and discuss how we might use $c$ to chart and classify the space of CFTs and QFTs.


 

Junior Strings is a seminar series where DPhil students present topics of common interest that do not necessarily overlap with their own research area. This is primarily aimed at PhD students and post-docs but everyone is welcome.
