Mathematrix: What is a minority in Mathematics?

Abstract

A question we get asked all the time! We'll also be discussing the numerous ways our identities as Mathematicians are shaped by being a minority. Free lunch provided.

Oxford Women and Non-Binary People in Mathematics Day 2025: Pathways to Progress

Saturday 1st March 2025 - 10-4:30 - Mathematical Institute

Building on the success of last year's conference, this year's event, 'Pathways to Progress' will showcase the varied paths that women and non-binary people can take within Maths, from art to teaching to academia to tech. We will be bringing together mathematicians from across the UK for a schedule of talks, workshops, and networking sessions. The aim is to encourage women and non-binary people to pursue careers in Mathematics, to promote women and non-binary role models, and to bring together a community of like-minded people.

This event is open to everyone, regardless of their gender identity. More details can be found on our website https://www.oxwomeninmaths.co.uk/ and the registration form is here.

How to recognise black hole states?

Pieter Bomans
Abstract

Black holes play a central role in our understanding of quantum gravity, but identifying their precise counterparts in a dual QFT remains a tricky business. These states are heavy, chaotic, and encode various universal aspects — but are also notoriously hard to characterise. In this talk, we’ll explore how supersymmetric field theories provide a controlled setting to study black hole states. In particular, we’ll introduce the idea of fortuitous states as a useful criterion for identifying BPS black hole states. We’ll then illustrate this concept with concrete examples, including the (supersymmetric) SYK model and the D1-D5 CFT.

 

The discussion will be based on the following recent papers:
arXiv:2402.10129, arXiv:2412.06902, and arXiv:2501.05448.

Statistical Mechanics of Signed Graphs

Anna Gallo
(IMT School for Advanced Studies)
Abstract

Networks provide a powerful language to model interacting systems by representing their units as nodes and the interactions between them as links. Interactions can be connotated in several ways, such as binary/weighted, undirected/directed, etc. In the present talk, we focus on the positive/negative connotation - modelling trust/distrust, alliance/enmity, friendship/conflict, etc. - by considering the so-called signed networks. Rooted in the psychological framework of the balance theory, the study of signed networks has found application in fields as different as biology, ecology, economics. Here, we approach it from the perspective of statistical physics by extending the framework of Exponential Random Graph Models to the class of binary un/directed signed networks and employing it to assess the significance of frustrated patterns in real-world networks. As our results reveal, it critically depends on i) the considered system and ii) the employed benchmark. For what concerns binary directed networks, instead, we explore the relationship between frustration and reciprocity and suggest an alternative interpretation of balance in the light of directionality. Finally,  leveraging the ERGMs framework, we propose an unsupervised algorithm to obtain statistically validated projections of bipartite signed networks, according to which any, two nodes sharing a statistically significant number of concordant (discordant) motifs are connected by a positive (negative) edge, and we investigate signed structures at the mesoscopic scale by evaluating the tendency of a configuration to be either `traditionally' or `relaxedly' balanced.
