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)

A low-rank technique for computing the quasi stationary distribution of Galton-Watson processes – Stefano Massei (EPFL)
Place: Sala Seminari Ovest, Dipartimento di Informatica. Branching processes describe the dynamics of a population of individuals which reproduce and die independently, according to some specific probability distributions. More precisely, we assume…
