A half-century ago when simply elliptic singularity was introduced, it was a natural question whether its discriminant complement is a $K(\pi,1)$ space. At that time, Fulvio Lazzeri suggested the possibility of the existence of a…

Abelian dynamical Galois groups – Andrea Ferraguti (SNS, Pisa)
Dynamical Galois groups are invariants associated to dynamical systems generated by the iteration of a self-rational map of $\mathbb{P}^1$. These are still very mysterious objects, and it is conjectured that abelian groups only appear in very…
Dispersive effects on domains with boundary: what we know and what we don’t\u2028 – Fabrice Planchon (Paris IV)
We discuss a series of recent results about dispersive equations on domains, with particular interest in the so called Strichartz estimates. We shall discuss along the talk some open questions as well. The seminar will be only in presence, those…
Finite Energy Weak Solutions of the Navier-Stokes-Korteweg equations – Stefano Spirito
In this talk I will present some results concerning the analysis of the existence of finite energy weak solutions of the Navier-Stokes-Korteweg equations, which model the dynamic of a viscous compressible fluid with capillarity effect. These kind of…
Caputo and Riemann-Liouville fractional derivatives: a matrix comparison – Mariarosa Mazza (Università dell’Insubria)
Fractional derivatives are a mathematical tool that receivedmuch attention in the last decades because of their non-local behaviorwhich has been demonstrated to be useful when modeling anomalousdiffusion phenomena appearing, e.g., in imaging or…
On the convex components of a set – Giorgio Stefani (University of Basel)
The convex components of a set (with non-empty interior) are not uniquely determined in general. In this talk, after having recalled some elementary (quantitative) monotonicity properties of the Euclidean perimeter, we study some lower bounds on the…
Rigidità di varietà iperboliche con bordo geodetico – Viola Giovannini (University of Luxembourg/Università di Pisa)

Topology of Lagrangian fibrations and $P=W$ phenomena on irreducible symplectic varieties – Camilla Felisetti (Università di Trento)
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.…
