Dienstag, 12.05.2026: "Je suis Sophie Germain/I am Sophie Germain" -- movie screening on May 12
*
May 12, the birthday of Maryam Mirzakhani, is dedicated to celebrating women in mathematics. Join us for a screening of the short movie "Je suis Sophie Germain/I am Sophie Germain" -- just 15(!) minutes -- and if you like, stay for an informal discussion of the movie, the life and work of Sophie Germain, and of women in mathematics then and today. We also invite to fill out the following short questionnaire, even if you’re not planning to attend: https://forms.gle/R4hzRZY74rQcmytKA We hope to see you all on May 12, 16:15 in lecture hall N14. There will be cookies.

Freitag, 15.05.2026: The liquid-vapor phase transition in a system with a finite but coarse-grained attraction
Dr. Ian Jauslin (Rutgers)
The standard approach to studying the liquid-vapor phase transition uses the Maxwell double-tangent construction. Whereas this construction is easily justified physically, deriving it mathematically has proved to be more difficult. In 1966, Lebowitz and Penrose proved the Maxwell construction in a mean field model, where the particles interact via a hard-core repulsion, and an infinite range, infinitely weak attraction. Generalizing their result to finite pair attractions remains an open problem. In this talk, I will discuss a proof of the existence of a liquid-vapor phase transition in a system with an attraction that is finite, but is also coarse-grained. More precisely, we split up space into mesoscopic boxes, and define an attraction that ignores the location of the particles within each box. Defined in this way, our model is reflection positive, which allows us to prove the existence of a liquid-vapor phase transition. This is joint work with Qidong He, Joel L. Lebowitz, and Ron Peled.
