Dear all,
I forward the following announcement from the Probability research group, which is interesting also for people working in Math Analysis in general. Info below.
The seminarhttps://www.dm.unipi.it/en/seminar/?id=68c88256fc368dd2a765119c will take place on THURSDAY, 25.09.2025 at 09:00 CEST in Aula N1, Polo Fibonacci, UNIPI and streamed online at this link: https://meet.google.com/gji-phwo-vbg
Best regards, Luigi
Speaker: Michele Coti Zelati (Imperial College London)
Title: Alpha-unstable flows and the fast dynamo problem
Abstract: The fast dynamo problem concerns the generation and maintenance of magnetic fields by fluid motion through the process of electromagnetic induction. In passive vector advection, this can be formulated as the exponential growth of the magnetic energy, at a resistivity-independent rate. In this talk, I will provide a construction of a Lipschitz, divergence-free and time-independent velocity field that is a fast dynamo on the whole space.
