Please join us for our annual Pride Picnic. This event is open to all within MPLS who are part of the LGBTQIA+ community. 

We will meet at 1pm in University Parks but drop by when convenient. We will provide a rainbow of snacks, but feel free to bring your own lunch. We’ll be just along South Walk between the two paths from Keble Gate towards the river.

Data-Adaptive Weight-Ensembling for Multi-task Model Fusion
Tang, A Shen, L Luo, Y Liu, S Hu, H Du, B Tao, D International Journal of Computer Vision 1-17 (25 Apr 2025)

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.

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.

Another mathematical parable from the Book of Josh.

30 years since the Galois characterisation of ℚₚ — Part II.

Benedikt Stock
(University of Oxford)
Abstract

Building on Leo’s talk last week, I will present the full Galois characterisation of henselianity and introduce some of the ‘explicit’ ingredients he referred to during his presentation. In particular, I will describe a Galois cohomology-inspired criterion for distinguishing between different characteristics. I will then outline the full proof of the Galois characterisation of p-adically closed fields, indicating how each of the ingredients enters the argument.
