Eventi
Elliptic Artin Monoids and Higher Homotopy Groups – Kyoji Saito (RIMS, Japan)
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…
On modified quasilinear Schrödinger equations: a variational approach – Caterina Sportelli (Università di Bari)
In the last years, quasilinear Schrödinger-type equations became a topic of wide interest and they have been derived as a model of several physical phenomena. In this talk, after having recall some classical variational tools, we study the existence…
Spazi di moduli e teoria delle rappresentazioni – Francesco Sala (Università di Pisa)

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…
