Semplificare frazioni online dating

In this seminar I would like to address some of these question through two recent developed tools: a Lagrangian representation of the solution u and a quadratic estimate on the variation of the speed of its characteristic fronts. More recently, motivated by problems arising in random matrix theory, people have tried to apply these methods in very large dimensions.However the regularity of optimal maps seem to play an important role in this context, and unfortunately one cannot hope in general to obtain regularity estimates that are uniform with respect to the dimension.Based on these considerations, it seems hopeless to apply optimal transport theory in this context.Still, ideas coming from optimal transport can be used to construct approximate transport maps (i.e., maps which send a density onto another up to a small error) which enjoy regularity estimates that are uniform in the dimension, and such maps can then be used to show universality results for the distribution of eigenvalues in random matrices.Si tratta di una vera e propria interazione in entrambe le direzioni che, è importante sottolinearlo, ha stimolato notevoli sviluppi matematici.Dopo aver discusso alcuni aspetti di questa interazione, evocherò alcune sfide di oggi.indietro 15 Venerdı̀ 11 ore 9 aula CD Structure of solutions for general systems of conservation laws *Stefano BIANCHINI SISSA Trieste The theory of BV solutions to system of conservation laws ut f (u)x = 0 u ∈ Rn , f : Rn → Rn , which are the natural extension of the scalar equation n = 1 where the flux f is convex or with finitely many inflection point, is in some sense complete: there are sharp results on the well-posedness, stability and structure of the solution.

Modena, Lagrangian representation for solution to general systems of conservation laws, in preparation. Apart from its applications to economics, optimal transport theory is an efficient tool to construct change of variables between probability densities, and this fact can be applied for instance to prove stability of minimizers of several geometric/functional inequalities.

Tale metodo ha permesso di dimostrare svariati risultati (e.g., il mescolamento esponenziale per i flussi geodetici, stime precise dell’errore nel calcolo del numero di orbite periodiche e proprietà meromorfiche di opportune funzioni zeta).
