The Alan Tayler Lecture 2023 - The Maths (and Engineering) of Moving People and Things Around

Eddie Wilson
(St Catherine's College)
Further Information

St Catherine’s College has a long tradition in applied and industrial mathematics and has hosted an annual series of lectures on Mathematics and its Applications since 1986. In 1995, the series was renamed in memory of Alan Tayler, in tribute to his efforts and achievements in this field. Alan was the first Fellow in Applied Mathematics to be appointed at St Catherine’s. His lifelong commitment was to the practical application of mathematical ideas to problems in science and industry. His vision continues to inspire many national and international collaborations on the theme of mathematics-in-industry.

The Zilber-Pink conjecture: a review

Chris Daw
(University of Reading)
Abstract

I will recall the Zilber-Pink conjecture for Shimura varieties and give my perspective on current progress towards a proof.

New ideas in Arakelov intersection theory

Michał Szachniewicz
(Mathematical Insitute, Oxford)
Abstract

I will give an overview of new ideas showing up in arithmetic intersection theory based on some exciting talks that appeared at the very recent conference "Global invariants of arithmetic varieties". I will also outline connections to globally valued fields and some classical problems.

On the abelianization of the level 2 congruence group of the mapping class group.

Tara Brendle
Abstract

We will survey work of Birman-Craggs, Johnson, and Sato on the abelianization of the level 2 congruence group of the mapping class group of a surface, and of the corresponding Torelli group. We will then describe recent work of Lewis providing a common framework for both abelianizations, with applications including a partial answer to a question of Johnson.

How hard is it to know if there is an epimorphism from one group to another

Murray Elder
Abstract

Let C,D be classes of finitely presented groups. The epimorphism problem from C to D is the following decision problem:

Input: Finite descriptions (presentation, multiplication table, other) for groups  G in C and H in D

Question: Is there an epimorphism from G to H?

I will discuss some cases where it is decidable and where it is NP-complete. Spoiler alert: it is undecidable for C=D=the class of 2-step nilpotent groups (Remeslennikov).

This is joint work with Jerry Shen (UTS) and Armin Weiss (Stuttgart).

Forming a Thought into Form - Jon Keating, Maya B. Kronic, Emma Ridgway, and Conrad Shawcross with Fatos Ustek

Further Information

Turning thought in to form is a mysterious process with which artists, scientists, philosophers and, indeed, all of us engage. But though the outcomes, mathematical, artistic, philosophical, may be different, might there be much that is common to all?

In the last lecture of the four-part series organised as part of Conrad Shawcross' 'Cascading Principles' exhibition in Oxford Mathematics, we bring together a panel comprising Jon Keating, Sedleian Professor of Natural Philosophy at the University of Oxford, Emma Ridgway, Director of the Foundling Museum,  Maya B Kronicg, philosopher and Director of Urbanomic, and Conrad himself. The discussion will be chaired by Fatos Ustek, curator of the 'Cascading Principles' exhibition.

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

Please email @email to register for the in-person event.The lecture will be broadcast on the Oxford Mathematics YouTube Channel at a later date.
