Mimetic finite difference approximation of quasi-linear elliptic problems

In this talk we address the solution of quasilinear elliptic problems of monotone type by using the Mimetic Finite Difference (MFD) method. Under a suitable approximation assumption, we prove that the...

Numerical Simulation of Quasi-Geostrophic Turbulence

Il modello quasi-geostrofico è uno tra i piè semplici modelli volto alla descrizione della circolazione atmosferica per i flussi a larga scala extra-tropicali (scale sinottiche). Presenterò il modello...

A comparison between different cycle decompositions for Metropolis dynamics

In the last decades the problem of metastability has been attacked on rigorous grounds via many different approaches and techniques which are briefly reviewed in this paper. It is then useful to under...
