We study the speed of propagation of initial data for Hamilton-Jacobi equations with multiplicative rough (typically stochastic) time dependence. We first show that, in contrast with the classical (deterministic) case, in general this speed may be…

G.I.T. mon amour – Andrea Di Lorenzo (SNS Pisa)
Titolo: G.I.T. mon amour Abstract: Tutti noi amiamo formare quozienti di oggetti geometrici rispetto all’azione di qualche gruppo. In geometria algebrica non sempre questo è possibile, o almeno non in maniera soddisfacente. Nel seminario introdurrò…
Periodicity as dimension: NLS ground states on periodic metric graphs – Simone Dovetta (Politecnico di Torino)
The talk introduces and discusses some recent results on the existence of mass constrained ground states for stationary nonlinear Schrodinger equations on periodic metric graphs. Even though every metric graph is locally a one–dimensional structure,…
Il Crittografo nel 2019 – Massimiliano Sala (Università di Trento)
Le persone che lavorano abitualmente in Crittografia sono, in gran parte, raggruppabili in tre grandi categorie. Ci sono quelli governativi,…
Generalised solutions via set optimization of Hamilton-Jacobi equation for multi objective cost – Daniela Visetti (Free University of Bozen-Bolzano)

Lagrangian mean curvature flow of Whitney spheres – Andreas Savas-Halilaj (University of Ioannina)
We investigate the evolution under the mean curvature flow of an equivariant Lagrangian sphere. It is shown that under a convexity assumption on the Ricci curvature, the flow develops a type-II singularity that rescales to the product of a grim…
Le coordinate di Fenchel-Nielsen sullo spazio di Teichmüller – Agnese Janigro (Università di Pavia)
Data una superficie chiusa orientabile di genere g>1 è possibile studiare lo spazio delle metriche riemanniane iperboliche su di essa, ossia quelle con curvatura costante pari a – 1. In questo seminario sarà presentato lo spazio di Teichmüller, che…
On the metric perurbation for semilinear wave equations – Hideo Kubo (Hokkaido University)
On the metric perurbation for semilinear wave equations Abstract: In this talk I’d like to revisit a joint work with Professor Katayama in which we dealt with a system of two-components semilinear wave equations. We assume the nonlinearity of one…
Computing dependability-oriented measures on Markov chains by means of matrix functions – Giulio Masetti (ISTI-CNR)
In the context of computing and communication system, dependability is defined as the ability to deliver service that can justifiably be trusted. Dependability is then an umbrella term that encompasses several attributes, such as: availability,…
Geometry of random eigenfunctions and Wiener chaos – Maurizia Rossi (Université Paris Descartes)
