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.

SPASS nasce nel 2011 per raccogliere i seminari sui temi che ne compongono l'acronimo organizzati a Pisa, al Dipartimento di Matematica e alla Scuola Normale Superiore. A partire dal 2022 la piattaforma si estende al gruppo di ricerca in Probabilità delle Università di Firenze e Siena.
SPASS dates back to 2011, when it was created as a joint seminar group in Pisa on the subjects composing the acronym, at the Department of Mathematics and Scuola Normale Superiore. In 2022 the research groups in Probability Theory of Universities of Florence and Siena joined the group.
