Anomalous Regularization in Kazantsev-Kraichnan Model
Marco Bagnara, Francesco Grotto, Mario Maurelli
This work investigates a passive vector field which is transported and stretched by a divergence-free Gaussian velocity field, delta-correlated in time and poorly correlated in spa…

Anomalous Regularization in Kraichnan's Passive Scalar Model
Lucio Galeati, Francesco Grotto, Mario Maurelli
We consider the advection of a passive scalar by a divergence free random Gaussian field, white in time and Hölder regular in space (rough Kraichnan's model), a well established sy…

Existence of Invariant Measures for Stochastic Inviscid Multi-Layer Quasi-Geostrophic Equations
Federico Butori, Francesco Grotto, Eliseo Luongo +1
We consider an inviscid 3-layer quasi-geostrophic model with stochastic forcing in a 2D bounded domain. After establishing well-posedness of such system under natural regularity as…
