Envisioning Imagination - Roger Penrose, Carlo Rovelli and Conrad Shawcross with Fatos Ustek - SOLD OUT

Various
Further Information

Imagination is the creative force for artists. But what about mathematicians and scientists? What part does imagination play in their work? What do the artist and the scientist have in common? And how do each envision things that will never be seen?

In this panel discussion two scientists and one artist, all leaders in their field, will provide an answer. They have more in common than you would think.

Nobel-prize winning scientist Roger Penrose is Emeritus Rouse Ball Professor in Oxford. Carlo Rovelli is a Professor in the Centre de Physique Théorique de Luminy of Aix-Marseille Université and the author of several popular-science books including 'Seven Brief Lesson on Physics'. Conrad Shawcross is an artist specialising in mechanical sculptures based on philosophical and scientific ideas. His exhibition, 'Cascading Principles' is currently showing in the Mathematical Institute.

The discussion will be chaired by curator and writer Fatos Ustek, curator of the 'Cascading Principles' exhibition.

There will be an opportunity to view the exhibition from 4pm on the day of the lecture.

Fluctuating Systems Workshop in Oxford

The workshop "Interacting particles, fluctuating systems, and SPDEs" will take place at the Mathematical Institute from 8-10 June 2023. The goal of the conference is to to bring together researchers in diverse areas of stochastic analysis, with a focus on interacting particle systems, stochastic PDEs, and some aspects of homogenization. Please feel welcome to attend the talks and coffee even if you have not registered, and for further information see the website

Holographic description of code CFTs

Anatoly Dymarsky

Abstract

Recently, a relation was introduced connecting codes of various types with the space of abelian (Narain) 2d CFTs. We extend this relation to provide holographic description of code CFTs in terms of abelian Chern-Simons theory in the bulk. For codes over the alphabet Z_p corresponding bulk theory is, schematically, U(1)_p times U(1)_{-p} where p stands for the level. Furthermore, CFT partition function averaged over all code theories for the codes of a given type is holographically given by the Chern-Simons partition function summed over all possible 3d geometries. This provides an explicit and controllable example of holographic correspondence where a finite ensemble of CFTs is dual to "topological/CS gravity" in the bulk. The parameter p controls the size of the ensemble and "how topological" the bulk theory is. Say, for p=1 any given Narain CFT is described holographically in terms of U(1)_1^n times U(1)_{-1}^n Chern-Simons, which does not distinguish between different 3d geometries (and hence can be evaluated on any of them). When p approaches infinity, the ensemble of code theories covers the whole Narain moduli space with the bulk theory becoming "U(1)-gravity" proposed by Maloney-Witten and Afkhami-Jeddi et al.
