Seminario di Probabilità e Finanza Matematica

Martedì 19 Novembre 2013 alle ore 16:00 in Aula 1AD100 Francesco Morandin dell'Università di Parma terrà un seminario intitolato "Anomalous dissipation in a stochastic inviscid shell model of turbulence".

Abstract
Shell models of turbulence are infinite systems of coupled nonlinear equations with exponentially-growing coefficients. They are thought to be able to capture some of the statistical properties and features of three-dimensional turbulence, while presenting a structure much simpler than Navier-Stokes and Euler equations. We introduce a stochastic version with multiplicative noise of some of these models and prove energy dissipation in spite of its formal conservativity.
