A raising operator formula for Macdonald polynomials – George H. Seelinger (University of Michigan)
Macdonald polynomials are a basis of symmetric functions with coefficients in $\mathbb{Q}(q,t)$ exhibiting deep connections to representation theory and algebraic geometry. In particular, specific specializations of the $q,t$ parameters recover…
Thermodynamic formalism in dynamical systems – Paulo Varandas (Universidade Federal da Bahia)
The modern theory of Dynamical Systems aims to describe the asymptotic behavior and complexity of maps and flows, with the intervention…
Handle numbers of knots and sutured manifolds – Kenneth L. Baker (University of Miami)
The handle number, or Morse-Novikov number, of a knot counts the minimum number of handles needed for a circular Heegaard…
The J-invariant of linear algebraic groups of outer type – Nikita Geldhauser (LMU Munich)
The J-invariant is a discrete invariant of semisimplealgebraic groups which describes the motivic behavior of the variety ofBorel subgroups. This invariant was an important tool to solve severallong-standing problems. For example, it plays an…
From linear to nonlinear model order reduction: some results and perspectives – Giovanni Stabile (Università di Urbino)
Non-affine parametric dependencies, nonlinearities, and advection-dominated regimes of the model of interest can result in a slow Kolmogorov n-width decay,…
Pretalk: Handle numbers of knots and sutured manifolds – Kenneth L. Baker (University of Miami)
Introductory talk for the Geometry Seminar.…
Monodromy kernels for strata of abelian differentials – Riccardo Giannini (University of Glasgow)
In this talk, we are going to talk about the topology of the moduli space of translation surfaces. These are closed Riemann surfaces with a flat metric on the complement of some finite number of points, around which the metric is given by cyclically…
Sharp asymptotics for the Allen-Cahn equation in the limit of small noise and large volume – Giacomo di Gesù (Roma La Sapienza)
We consider the Allen-Cahn equation on a finite interval perturbed by space-time white noise. Keeping the size of the spatial…
Weak coupling scaling of critical SPDEs – Giuseppe Cannizzaro (University of Warwick)
The study of stochastic PDEs has known tremendous advances in recent years and, thanks to Hairer’s theory of regularity structures…
