SQUIDS Seminar: Optimizing the Dynamics of the Frequency Bias in Fourier Features Neural Networks
12:00 - 13:00 29 April 2026
Speaker: Professor Matias Courdurier (Pontifical Catholic University of Chile) Abstract: Implicit Neural Representations often learn signals capturing low-frequency structure before high-frequency details, a phenomenon known as Frequency Bias. Fourier Feature networks can reduce this effect by encoding...

Logic Seminar - Orla McGrath
14:00 - 15:00 29 April 2026
Speaker: Orla McGrath (University of Leeds) Title: Partial Difference Algebraic Groups Abstract: A difference algebraic group is a subgroup of the general linear group defined by difference equations. Groups definable in ACFA (algebraically closed fields with an automorphism) have been widely studied,...

Heilbronn Algebra Seminar - Pete Gautam
13:00 - 14:00 28 April 2026
Title: Fusion systems related to large sporadic groups Abstract: Fusion systems are closely related to groups where we focus only on conjugation (fusion) coming from the group to its p-subgroups. Fusion systems related to sporadic groups have been studied throughout, and many exotic fusion systems have...

Manchester Number Theory Seminar - Sean Prendiville (Lancaster)
14:00 - 15:00 28 April 2026
Speaker: Sean Prendiville (Lancaster) Title: Regularity as an alternative to transference Abstract: One way to approach certain number-theoretic problems involving sparse sets, such as the primes or squares, is to "model" these sets with dense sets of integers, then import results from the dense regime....

Dynamical Systems and Analysis Seminar - Konstantin Bogdanov
12:00 - 13:00 27 April 2026
Speaker: Konstantin Bogdanov (University of Manchester) Title: Infinite-dimensional Thurston theory in holomorphic dynamics Abstract: Thurston's Topological Characterization of Rational Functions is one of the main tools in complex dynamics. It provides a criterion of when a topological model of a...
