Title: Hölder continuous solutions to inhomogeneous incompressible Euler flows
Abstract: In this talk, we shall discuss about the construction of global-in-time Hölder continuous weak solutions to density dependent incompressible Euler equations in three-dimensional periodic domain. The proof is based on convex integration techniques using Mikado flows as building blocks. As a main novelty with respect to the related literature, our result produces Hölder continuous density.

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.
