The Poisson structure on the affine Grassmannian via derived algebraic geometry – Valerio Melani (Università di Pisa)
Motivated by a conjecture of Kapranov-Ginzburg-Vasserot, we will explain how to reinterpret the classical Poisson structure on the affine Grassmannian using tools from derived symplectic (and Poisson) geometry. Our approach is based on the study of…
Stable commutator length e i suoi valori – Francesco Fournier-Facio (ETH Zürich)
Il seminario si svolgerà in Aula N (Polo Fibonacci). http://people.dm.unipi.it/babygeometri/index.html…
Microlocal analysis of singular measures – Nicolas Burq (Orsay)
In this talk, I will investigate the structure of singular measures from a microlocal perspective. I will introduce a notion of $L^1$- regularitywave front set for scalar and vector distributions. Our main result is a proper microlocal…
An introduction to dispersive equations – Nicolas Burq (Orsay)
This seminar is a quick introduction to the field of dispersive equations. We shall present the main models most studied in the literature as well as a quick overview of the techniques available in the literature.…
Convergence and ergodicity of splitting methods for fluid models – Andrea Agazzi (Duke University)
We consider a family of processes obtained by randomly splitting the deterministic flows associated to some fluid models (e.g. Lorenz 96, Galerkin-Naver-Stokes). These split dynamics allow to separate the conservative and dissipative part of the…
Structure-preserving dynamical model order reduction of parametric Hamiltonian systems – Cecilia Pagliantini (TU Eindhoven)
In real-time and many-query simulations of parametric differential equations, computational methods need to face high computational costs to provide sufficiently accurate and stable numerical solutions. To address this issue, model order reduction…
A variational approach to a class of nonlinear Cauchy-Neumann problems – Alessandro Audrito (ETH Zurich)
In this talk, I will present some recent results about existence and Holder regularity of weak solutions to a class of nonlinear Cauchy-Neumann problems arising in combustion theory and fractional diffusion. Weak solutions are obtained through a…
Partial and global representations of finite groups – Michele D’Adderio (Université Libre de Bruxelles, Belgium)
The notions of partial actions and partial representations have been extensively studied in several algebraic contexts in the last 25 years. In this talk, we introduce these concepts and give a short overview of the results known for finite groups.…
Alcuni risultati di confronto per soluzioni di problemi ellittici con dati al bordo di tipo misto – Cristina Trombetti (Università degli Studi di Napoli Federico IIi Federico II)
I risultati di confronto alla Talenti per soluzioni di problemi ellittici con dati al bordo di tipo Dirichet e Neumann sono stati ampiamente affrontati negli ultimi decenni. In questo seminario si affronta il problema di come ottenere risultati…
