Structure-preserving finite elements for the linearised Einstein-Bianchi system - a case study by Yizhou Liang

Einstein's equations describe how the curvature of spacetime relates to energy and mass. However, as analytical solutions are rarely feasible, numerical solutions of these equations on computers are indispensable and are crucial in modern astrophysics, such as the detection of gravitational waves. But there are problems...

The Pousaz Scholarships

We are delighted to announce the launch of the Pousaz Scholarship Programme, made possible through a grant from the Pousaz Philanthropies Foundation. Starting in September 2026, three cohorts of five Pousaz Scholars will join Oxford's Mathematical Institute to pursue an MSc in Mathematics or related subjects.

Large scale geometry and homotopical filling functions of groups - a case study by Jerónimo García Mejía

I study the large scale geometry of infinite groups and spaces, focusing on quasi-isometries, which are maps between groups or spaces that preserve the large scale geometry. Since quasi-isometries need not be continuous, distinguishing groups up to quasi-isometries can be challenging. This motivates considering invariants, that is, properties preserved under quasi-isometries.
