2025 Annual Disability Lecture: ‘Building an Environment for All’ starring Sam Howison

15 May, 6pm to 8pm, Lecture Theatre 1, Blavatnik School of Government and via Zoom

Our very own Sam Howison will consider how an institution like Oxford University might think about access issues as it maintains, refurbishes and rebuilds its workplace? Includes examples 'good and bad' from the Andrew Wiles Building - Sam was Head of the Mathematical Institute during its construction.

Blueprints: how mathematics shapes creativity - Marcus du Sautoy

In this Oxford Mathematics Public Lecture Marcus du Sautoy unpacks how we make art, why a creative mindset is vital for discovering mathematics, and how a fundamental connection to the natural world intrinsically links the two subjects. 

21 May, 5.30pm. Please email Dyrol (@email) to register to attend in person.

Relativistically invariant wave equations in the realist theory

Tristram de Piro
Abstract
Boris Zilber showed that you can build a logical structure around the relativistic Klein-Gordon and Dirac equations from quantum field theory. I will present the parallel realist theory, favoured by Einstein, to the Copenhagen interpretation. Starting from the requirements of Rutherford's principle for atomic systems and Maxwell's equations, I will show that there exist unique relativistically invariant wave equations for charge and current, with non-vacuum solutions, which predict the proportionality in the Balmer series.

Fields with the absolute Galois group of Q

Jochen Koenigsmann
(University of Oxford)
Abstract
This is a report on work in progress aiming to prove the conjecture that if the absolute Galois group of a field K is isomorphic to that of \Q then K admits a (possibly trivial) henselian valuation with divisible value group and residue field \Q. What I can prove is that such a field K has a unique ordering and unique p-adic valuations, and that K satisfies Cebotarev's density theorem, Kronecker-Weber, Hasse-Minkowski, quadratic reciprocity etc.
We will show that our conjecture is equivalent to the birational version of Grothendieck's Section Conjecture over \Q, and we will discuss a model theoretic strengthening of our conjecture.
