Bach, the Universe and Everything - The Beauty of Mathematics SOLD OUT

Vicky Neale and The Orchestra of the Age of Enlightenment
Further Information

Bach, the Universe and Everything is a partnership between Oxford Mathematics, Music at Oxford and the Orchestra of the Age of Enlightenment where we put on our very own Sunday service for curious minds; a place where music and science rub shoulders. And a place where you get to join in.

The Science
You’ve heard that some people find mathematics as beautiful as Bach’s music, but you’re not really sure why. Dr Vicky Neale is here to convince you it is, as she explores the intoxicating mysteries of prime numbers and how they push the limits of human understanding.

The Music
BWV 196 is one of Bach’s first cantatas, written when he was in his early twenties for a friend’s wedding. It features a striking soprano aria, and an overall theme of ‘partnership’, with two factions of instruments uniting to become one.

Hidden histories: Oxford’s female computing pioneers

Ursula Martin, Georgina Ferry and Panel
(University of Oxford)
Further Information

Join us in Oxford Mathematics on 27th February 2020 for a talk and discussion celebrating the Bodleian Libraries' release of interviews by Georgina Ferry of some of Oxford’s female computing pioneers.

Some remarkable women shaped Oxford computing: Dorothy Hodgkin won the Nobel Prize for work on insulin; Susan Hockey pioneered digital humanities; Shirley Carter, Linda Hayes and Joan Walsh got the pioneering software company NAG off the ground in 1970; and female operators and programmers were at the heart of the early large-scale computing efforts powering 20th-century science.

4.30pm: Welcome tea
5.00pm: Professor June Barrow-Green - Hidden histories: Oxford’s female computing pioneers
5.45pm: Panel discussion chaired by science writer Georgina Ferry and featuring some of the the pioneers themselves

Uniqueness & non-uniqueness results for wave equations

Jan Sbierski
(Oxford)
Abstract

A well-known theorem of Choquet-Bruhat and Geroch states that for given smooth initial data for the Einstein equations there exists a unique maximal globally hyperbolic development. In particular, time evolution of globally hyperbolic solutions is unique. This talk investigates whether the same result holds for quasilinear wave equations defined on a fixed background. After recalling the notion of global hyperbolicity, we first present an example of a quasilinear wave equation for which unique time evolution in fact fails and contrast this with the Einstein equations. We then proceed by presenting conditions on quasilinear wave equations which ensure uniqueness. This talk is based on joint work with Harvey Reall and Felicity Eperon.

The polynomial scattering equations on and off shell

Peter Goddard
(IAS Princeton)
Abstract

A polynomial form is established for the off-shell CHY scattering equations proposed by Lam and Yao. Re-expressing this in terms of independent Mandelstam invariants provides a new expression for the polynomial scattering equations, immediately valid off shell, which makes it evident that they yield the off-shell amplitudes given by massless ϕ3 Feynman graphs. A CHY expression for individual Feynman graphs, valid even off shell, is established through a recurrence relation.

Asymptotic stability of peaked travelling waves for Camassa-Holm type equations.

José Manuel Palacios
(Université de Tours)
Abstract

The Camassa-Holm (CH) equation is a nonlinear nonlocal dispersive equation which arises as a model for the propagation of unidirectional shallow water waves over a flat bottom. One of the most important features of the CH equation is the existence of peaked travelling waves, also called peakons. The aim of this talk is to review some asymptotic stability result for peakon solutions for CH-type equations as well as to present some new result for higher-order generalization of the CH equation.
