Irreducible holomorphic symplectic (IHS) varieties can be thought as a generalization of hyperkähler manifolds allowing singularities. Among them we can find for example moduli spaces of sheaves on $K3$ and abelian surfaces, which have been recently…

The Beris-Edward model for liquid crystals with absence of flow – Daniele Barbera (Università di Pisa)
In this talk I’ll present my master’s thesis project, focused on the Beris-Edward model. This system studies the behaviour of a molecule in a flux of nematic liquid crystals, a state of matter intermediate between the solid state and the liquid one.…
Varietà iperboliche che fibrano su S^1 – Matteo Migliorini (Scuola Normale Superiore)
Il seminario si terrà in Aula Magna. Per ulteriori informazioni:http://people.dm.unipi.it/babygeometri/index.html…
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.…
