Tipping points (critical transitions) are abrupt, often irreversible shifts in dynamical systems that can be triggered by small changes. This talk tackles two questions: how to predict tipping early and why tipping occurs. In this talk, I will...

Vertex operator algebras (VOAs) are algebraic objects that arose in the study of infinite dimensional lie algebras, mathematical physics, and in the classification of finite simple groups. These days they are understood to give rise to vector bundles...

For a finite-dimensional algebra A over an algebraically closed field k, varieties of finite-dimensional A-modules offer a geometric perspective on the homological and categorical properties of A and its modules. These varieties parametrize vector...

Join us for a day of interactive Math games, FREE mini pie and a chance to claim free passes to Project Hail Mary premiere! Pi Day at the Space Centre: A Perfectly Sweet Celebration of Math & Space 🥧🚀 This March 14, celebrate the most famous number...

Minimizing energy dissipation in driven stochastic systems is a fundamental goal in nonequilibrium thermodynamics. In the linear-response (slow driving) regime, this becomes a problem of Riemannian geometry: The control space is equipped with a...

Filtering is a core task in many areas of science and engineering, including weather and climate prediction, where it is known as data assimilation. It involves estimating the conditional probability distribution of a dynamical system's states given...

Abstract: In the classical setting of x2 and x3 acting on the circle group, the original (and unsolved) Furstenberg Conjecture is that the only continuous probability measure simultaneously invariant under both is Lebesgue measure. A stronger...

The volume spectrum is an analogue of the Laplace spectrum, defined through the area functional together with homological or cohomological relations in the space of hypercycles. In this talk, I will introduce several versions of the volume spectrum...

We construct explicit examples of abelian surfaces whose 2-torsion Galois representations are not self-dual. Such surfaces are necessarily not principally polarized. We consider abelian surfaces with a polarization of type (1,2) instead. Our main...

Lie group integrators are a class of numerical schemes for the solution of ordinary differential equations on manifolds. These methods avoid explicit representation of the solution in a coordinate chart by advancing the solution using a continuous...
