Título: Stability in Gagliardo-Nirenberg and (Log) Sobolev inequalities. Conferenciante: Nikita Simonov (Sorbonne Université, Paris). Resumen: In certain functional inequalities, the best constants and minimizers are known. The next natural question concerns stability: if a function “almost attains equality,” in what sense is it close to one of the minimizers? WeContinue Reading

IMAG Functional Analysis Seminar Title: Espacios inyectivos y sus amigos By Esteban Martínez Vañó (UGR) Abstract: En una primera sesión se presentarán los espacios inyectivos y la demostración del teorema de Kelley que afirma que todo espacio 1-injectivo es isométrico a un C(K) con K extremadamente disconexo.En una segunda sesiónContinue Reading

Título: Mean-field limit of particle systems over hypergraphs. Conferenciante: Nastassia Pouradier Duteil (Sorbonne Université, Paris). Resumen: We present a generalization of non-exchangeable particle systems with higher-order interactions, by removing two important assumptions that are usually made in particle systems: that of exchangeability of particles, and that of superposition of binaryContinue Reading

Title: Finite-velocity random motions and reset at the origin: Recent advances on transient and limit behaviors. Speaker: Antonio di Crescenzo (Department of Mathematics, University of Salerno).
