Buongiorno, trovate qui sotto l'avviso di seminario. Tutte le persone interessate sono cordialmente invitate. Cordiali saluti, Enrico Scalas -- Il giorno 9 ottobre 2026 alle ore 10 in aula 24 del Dipartimento di Scienze Statistiche, Sapienza Università di Roma, la Prof. Barbara Ruediger (Universitaet Wuppertal) presenterà un seminario dal titolo: Boltzmann Processes Riassunto: In [1] we identify the stochastic process which has, as the corresponding Fokker-Planck equation, the Boltzmann equation. This means that we identify the stochastic process which describes the dynamics in position and velocity of one molecule of a rarefied gas which expands in a vacuum according to the Boltzmann equation. We call this the Boltzmann process. We show that this is the solution of a McKean-Vlasov type stochastic differential equation with Poisson noise. All cases are considered here: hard sphere cut-off case, considered by Boltzmann, as well as soft and hard potentials. In [2] we prove the existence of the solution of this Mc Kean-Vlasov SDE for the hard sphere cut-off case. Bibliografia [1] On the construction and identification of Boltzmann processes, S.
