Buongiorno, segnaliamo da parte di Marco Ghimenti il seminario "Between Maxwell and Born–Infeld" che sarà tenuto da Pietro D'Avenia (Politecnico di Bari) il prossimo 17 aprile alle 17:30 in Aula Seminari. Riportiamo qui sotto l'abstract. A presto, Ilaria Lucardesi e Luigi Forcella -------- Speaker: Pietro D'Avenia (Politecnico di Bari) Title: Between Maxwell and Born–Infeld Abstract: We present some recent results on a model of electromagnetic theory obtained from a Lagrangian density Lq, depending on the parameter q. For q = 1, Lq corresponds to the Born–Infeld Lagrangian density and, for q = 2, it restores the Maxwell one.

Trovate qui sotto gli abstract. A presto, Ilaria Lucardesi e Luigi Forcella --------------------------------------------- Dear all, next week, for the Mathematical Analysis Seminar, there will be two seminars: on Tuesday 16th April at 5PM, in "Aula Seminari", we will have the pleasure of listening to Stefanos Georgiadis (KAUST). The title of the talk<https://www.dm.unipi.it/en/seminar/?id=6602fa9a282479bbfbbb1ff6> is "Uniqueness of renormalized solutions for the Maxwell-Stefan cross-diffusion system"; on Thursday 18th April at 5PM (+ snack at 4:45PM), in "Aula Riunioni", we will have the pleasure of listening to Anna Kausamo (Università degli Studi di Firenze). The title of the talk<https://www.dm.unipi.it/en/seminar/?id=6617a944282479bbfbbf84a2> is "The sufficiency of c-cyclical monotonicity for the optimality of transport plans". Please find below the two abstracts. See you soon, Ilaria Lucardesi and Luigi Forcella --------------------------------------------- Speaker: Stefanos Georgiadis (KAUST) Title: Uniqueness of renormalized solutions for the Maxwell-Stefan cross-diffusion system Abstract: Cross-diffusion systems are strongly coupled parabolic systems describing phenomena in which multiple species diffuse and interact with one another, e.g. in fluid mechanics or population dynamics. Although many methods have been developed to study existence of weak solutions to such systems, uniqueness is in general an open problem. To this degree, we study a particular cross-diffusion system, known as the Maxwell-Stefan system which describes diffusive phenomena in a multicomponent system of gases. We employ renormalized solutions and give conditions under which such solutions are unique. We, then, study the relation between weak and renormalized solutions, allowing us to identify conditions that guarantee uniqueness of weak solutions. The proof is based on an identity for the evolution of the symmetrized relative entropy. Using the method of doubling the variables we derive the identity for two renormalized solutions and use information on the spectrum of the Maxwell-Stefan matrix to estimate the symmetrized relative entropy and show uniqueness. ********** Speaker: Anna Kausamo (Univ. Firenze) Title: The sufficiency of c-cyclical monotonicity for the optimality of transport plans Abstract: c-cyclical monotonicity is the most important optimality condition of a transport plan. In this talk I will present a Gamma-convergence-based strategy, developed by myself and Luigi De Pascale, to prove the sufficiency of cyclical monotonicity for optimality in the multi-marginal $L^\infty$-optimal transport case that had previously been elusive.

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.

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.
