SQUIDS Seminar: From X-ray to Nonabelian Ray Transforms
12:00 - 13:00 8 October 2025
Speaker: Shubham Jathar (LUT University, Finland) Abstract: This talk surveys ray transforms in tomography, starting from the classical X-ray (Radon) transform and its geodesic generalization on Riemannian manifolds. We then discuss attenuated models with scalar and matrix weights, followed by nonabelian...

Heilbronn Algebra Seminar - Ben Smith
13:00 - 14:00 7 October 2025
Title: Coxeter matroids, minuscule varieties and Plücker equations Abstract: A matroid is a combinatorial object that can be seen as an abstraction of a linear space. For example, it is defined via a basis exchange relation, and every linear space gives rise to an underlying matroid. However, there...

Manchester Number Theory Seminar - Ilaria Cruciani
14:00 - 15:00 7 October 2025
Speaker: Ilaria Cruciani (Roma Tre/Manchester) Title: Finiteness in powers of elliptic schemes over cyclotomic extensions Abstract: A central theme in number theory is understanding when sets of rational or algebraic points on varieties are finite or infinite. Classical results, such as Northcott’s...

Dynamical Systems and Analysis Seminar - Laurent Bartholdi
13:00 - 14:00 6 October 2025
Speaker: Laurent Bartholdi (CNRS Lyon) Title: Hyperbolic correspondences Abstract: In joint work with Dima Dudko and Kevin Pilgrim, we consider certain correspondences on a Riemann surface, and show that they admit a weak form of hyperbolicity: su?iciently long loops get shorter under lifting at a...
