Dynamical Systems and Analysis Seminar - Dan Rust
Speaker: Dan Rust (Open University) Title: Substitution dynamical systems on compact alphabets Abstract: Substitution subshifts over finite alphabets are some of the simplest and best-known dynamical systems with a huge amount of literature devoted to them. In contrast, substitutions on infinite alphabets have been far less well-studied. In this...
Heilbronn Algebra Seminar - Bim Gustavsson: Sylow branching coefficients
Title: Sylow branching coefficients Abstract: In this talk we give a survey about the so-called Sylow branching coefficients; why they are interesting, what is known and what is not known.
AI Fun with ELLIS Invited Speaker Series | Aurelien Bibaut
Our invited speaker on 11 November will be Aurelien Bibaut from Netflix. Title: Safe Adaptive Policy Learning Abstract: Offline policy learning can require less information than accurate estimation of the full environment. We provide a two-step offline policy learning procedure that constructs policy proposals on one data split and selects a...
Logic Seminar - Andrew Brooke-Taylor
Speaker: Andrew Brooke-Taylor (University of Leeds) Title: Multiply-generated free shelves of embeddings Abstract: Large cardinal axioms are axioms that go beyond the usual ZFC axioms for set theory. One of the strongest known ones, referred to as I3, posits the existence of a non-trivial (i.e. not the identity) elementary embedding from an...
Probability Seminar: Anastasiia Kovtun
Anastasiia Kovtun (University of Manchester) will speak at the Probability seminar. Title: The Dickman Distribution: Historical Perspectives and New Multidimensional Generalisations Abstract: Since its introduction in the 1930s, the Dickman function has found applications in various fields, giving rise to several related objects, including the...
Pure maths colloquium - Richard Webb
Speaker: Richard Webb (University of Manchester) Title: Finding surface subgroups in mapping class groups Abstract: Many infinite groups can be studied by associating geometric spaces to them. Free groups, for example, act naturally on trees. The class of hyperbolic groups generalises this picture, in that they are modelled on spaces where geodesic...
SQUIDS Seminar: Bill Lionheart
Speaker: Bill Lionheart (University of Manchester) Title: At last an SVD for EIT Abstract: 40 years ago when I started working on Electrical Impedance Tomography I thought I should look for an analytical form of the singular value decomposition of some simplified linearized case. I would like to report some modest progress..... An interesting...
Statistics Seminar - Emma Gardner & Claudia Acerini (UK Centre for Ecology & Hydrology)
Title: Co-creating mechanistic models to increase understanding of species’ ecologies and support biodiversity-inclusive decision-making Abstract: In the UK, efforts are being made to promote ecosystem restoration and nature recovery across all policy scales – from national and local government through to grassroots community action. New incentives...
NASC-SQUIDS Joint Seminar: Parameter estimation for weakly interacting hypoelliptic diffusions
Speaker: Yuga Iguchi (Lancaster) Abstract: I will discuss mean-field-type stochastic differential equations (SDEs) and the estimation of their unknown parameters from discretely observed trajectories. These models describe systems of N weakly interacting particles, each governed by an SDE, with a possibly degenerate diffusion matrix. A central...
Heilbronn Algebra Seminar - Lewis Topley: Quantizations of coadjoint orbit closures in positive characteristics
Title: Quantizations of coadjoint orbit closures in positive characteristics Abstract: If g = Lie(G) is the Lie algebra of an algebraic group over a field of characteristic zero then the closures of coadjoint orbits are Poisson varieties and it is natural and interesting to study their quantizations. Losev showed that when G is simple the quantizations...
