Dear all,

Here is the announcement of the next MAP seminar.

⟶ Thursday 19 December, at 11:30 in Aula Riunioni.

⟶ Speaker: *Eliseo Luongo* (Universität Bielefeld)

⟶ Title: *Mean-Field Magnetohydrodynamics Models as Scaling Limits of Stochastic Induction Equations*

⟶ Abstract: We discuss some recent results on the asymptotic properties of a stochastic model for the induction equations of the magnetic field. These allow us to rigorously justify the mean-field equations introduced by Krause and Rädler and to find a dynamo effect in case of turbulence developed in a preferential direction. Time permitting, we will also discuss this problem from a Lagrangian view-point analyzing the properties of some Vlasov type equations associated with the evolution of the magnetic field. The talk is based on joint works with Federico Butori, Franco Flandoli and Yassine Tahraoui.

We remind you that these seminars are addressed to everybody: the first half of the seminar is dedicated to the introduction of notions and tools needed in the second half, which is focused on research topics.

See you soon,

The organizers: Michele Caselli Francesco Malizia
