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,…

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…

On generalized derivative NLS – Felipe Linares (IMPA )
In this talk we will present recent results concerning the initial value problem (IVP) associated to generalized derivative Schrödinger equations. We show local well-posedness for small initial data in a suitable weighted Sobolev spaces. We use an…
Perimeter with densities: an energy for epitaxial growth – Marco Caroccia
In this talk I will introduce a free energy, first studied by Ratz and Voigt, defined as the integration over the reduced boundary of a crystal E of a suitable psi(u(x)) where psi is a convex function and u denotes the adatom density (the density of…
Perturbation theory for the spectral decomposition of matrices – Marcus Carlsson (Lund University)
Consider a Hermitian matrix and a small perturbation. We will consider how the eigenvalues and eigenvectors change with the perturbation. Typical theorems concerning this either consider a perturbation along a line or provide general estimates valid…

On the positive definite solution of the nonlinear matrix equation X^p=A+M^T(X#B)M – Jie Meng (Pusan National University)
The nonlinear matrix equation X^p = A + M^T (X # B)M is considered, where p ≥ 1 is a positive integer, M is an n × n nonsingular matrix, A is a positive semidefinite matrix and B is a positive definite matrix. We call C # D the geometric mean of…
On the 1/H flow via p-Laplace approximation under Ricci lower bounds – Luciano Mari (Scuola Normale Superiore di Pisa)
In this talk, we consider the existence problem for weak solutions of the Inverse Mean Curvature Flow on a complete manifold with only a Ricci lower bound. Solutions either issue from a point or from the boundary of a relatively compact open set. To…
