See you soon, Ilaria Lucardesi and Luigi Forcella --------------------------------------------- Speaker: Andrea Pinamonti (Università degli Studi di Trento) Title: Lusin and Whitney theorems in Carnot groups: when geometry meets real analysis Abstract: Whitney extension results characterize when one can extend a mapping from a compact subset to a smooth mapping on a larger space. Lusin approximation results give conditions under which one can approximate a rough map by a smoother map after discarding a set of small measure. We first recall relevant results in the Euclidean setting, then describe recent work extending them to horizontal curves in the Heisenberg group.

See you soon, Ilaria Lucardesi and Luigi Forcella --------------------------------------------- Speaker: Ihsan Topaloglu (Virginia Commonwealth University) Title: A Variational model involving nonlocal interactions of Wasserstein type Abstract: In this talk I will consider a variational problem which appears in models of bilayer membranes. After introducing and deriving the model I will establish the existence of volume-constrained minimizers where the energy functional consists of two competing terms: a surface energy term penalizing transitions between sets and a nonlocal energy involving the Wasserstein distance between equal volume sets. In the second part of the talk I will consider the maximization of the minimum Wasserstein distance between two given sets, and show that this maximum is obtained by a micella. These results are drawn from joint works with Almut Burchard, Davide Carazzato, Michael Novack, and Raghavendra Venkatraman.

See you soon, Ilaria Lucardesi and Luigi Forcella --------------------------------------------- Speaker: L. Weng Title: Hypersurface with capillary boundary evolving by the mean curvature. Abstract: In this talk, we introduce a volume- or wetting area-preserving flow whose speed is given by the mean curvature with a non-local term for hypersurfaces with capillary boundary in the half-space. The non-local term creates additional difficulties, say for instance the comparison principle is no longer valid compared to locally constrained type flows. We demonstrate that for any convex initial hypersurface with a capillary boundary, the flow exists for all time and smoothly converges to a spherical cap as time goes to infinity.

Annuncio seminario "SPASS" - Leonardo Tolomeo

16 Feb '24

Care tutte e cari tutti, segnalo, anche da parte di Mario, il seminario "Transport of Gaussian measures under the flow of Hamiltonian PDEs: quasi-invariance and singularity" che sarà tenuto da Leonardo Tolomeo (Univ. of Edinburgh) martedì prossimo 20 Febbraio alle ore 14 in Aula Seminari. Il seminario è tra le attività SPASS, ma credo possa interessare anche gli analisti. Il link dell'evento è il seguente: https://www.dm.unipi.it/en/seminar/?id=65ccf769e7bee0277813b9eb Riporto per comodità anche l'abstract qui in basso. Luigi -------- Speaker: Leonardo Tolomeo (University of Edinburgh) Title: Transport of Gaussian measures under the flow of Hamiltonian PDEs: quasi-invariance and singularity Abstract: In this talk, we consider the Cauchy problem for the fractional NLS with cubic nonlinearity (FNLS), posed on the one-dimensional torus T, subject to initial data distributed according to a family of Gaussian measures. We first discuss how the flow of Hamiltonian equations transports these Gaussian measures. When the transported measure is absolutely continuous with respect to the initial measure, we say that the initial measure is quasi-invariant. In the high-dispersion regime, we exploit quasi-invariance to build a (unique) global flow for initial data with negative regularity, in a regime that cannot be replicated by the deterministic (pathwise) theory. In the 0-dispersion regime, we discuss the limits of this approach, and exhibit a sharp transition from quasi-invariance to singularity, depending on the regularity of the initial measure. This is based on joint works with J. Forlano (UCLA/University of Edinburgh) and with J. Coe (University of Edinburgh).

See you soon, Ilaria Lucardesi and Luigi Forcella --------------------------------------------- Title: Unconditional stability of equilibria in thermally driven compressible fluids Abstract: We show that small perturbations of the spatially homogeneous equilibrium of a thermally driven compressible viscous fluid are globally stable. Specifically, any weak solution of the evolutionary Navier–Stokes–Fourier system driven by thermal convection converges to an equilibrium as time goes to infinity. The main difficulty to overcome is the fact the problem does not admit any obvious Lyapunov function. The result applies, in particular, to the Rayleigh–Benard convection problem. Joint work with Yong Lu, Nanjing.
