Mathematrix Week 7 - In conversation with Philip Maini

Come along to room N3.12 on Wednesday 7th June from 1-2pm when we will be joined by Philip Maini, Professor of Mathematical Biology and Ethnic Minorities Fellow at St John's College, to discuss his mathematical journey and experiences. Signing up is not necessary but allows us to get a better idea of numbers.

An exact solution to cosmological bootstrap using 6j symbols

Sourav Sarkar
(Uppsala)
Abstract

We shall consider a crossing equation of the Euclidean conformal group in terms of conformal partial waves and in particular, a position independent representation of this equation. We shall briefly discuss the relevance of this equation to the problem of cosmological bootstrap. Thereafter, we shall sketch the derivation of the Biedenharn-Eliiot identity (a pentagon identity) for the 6j symbols of the conformal group and show how this provides us with an exact solution to said crossing equation. For the conformal group (which is non-compact), this involves some careful bookkeeping of the spinning representations. Finally, we shall discuss some consistency checks on the result obtained, and some open questions.

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
