TITLE: 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.
