In the talk we introduce the so-called mean field planning problem: a coupled system of PDEs, a forward continuity equation and a backward Hamilton-Jacobi equation. The problem can be viewed as a modification of the mean field games system as well…

On the local-global divisibility and the Tate-Shafarevich group – Gabriele Ranieri (Pontificia Universidad Catolica Valparaiso)
On the local-global divisibility and the Tate-Shafarevich group. Abstract: Let k be a global field and let A be a commutative algebraic group defined over k. Consider the following question : Problem. Let P be in A(k) and let q be a positive…
Gromov-iperbolicita` e generalizzazioni – Davide Spriano (ETH)
La teoria geometrica dei gruppi si occupa, come il nome suggerisce, dello studio dei gruppi tramite un approcio di tipo geometrico. Piu` precisamente, ad ogni gruppo si associa uno spazio metrico, tipicamente il rivestimento universale del complesso…
On the scaling limit of Onsager’s molecular model for liquid crystals – Yuning Liu (NYU University at Shanghai)
We study the small Deborah number limit of the Doi-Onsager equation for the dynamics of nematic liquid crystals. This is a Smoluchowski-type equation that characterizes the evolution of a number density function, depending upon both particle…
