Dear all, We are pleased to announce a seminar in Scuola Normale Superiore: SEMINARI DELLA CLASSE DI SCIENZE Simone Verzellesi Università di Padova Variational properties of the total inverse mean curvature in the plane under boundary constraints Abstract: In the Euclidean space, Aleksandrov's theorem asserts that smooth, closed, constant mean curvature hypersurfaces are round spheres. An effective proof of this result is provided by the characterization of the equality case in the so-called HeintzeKarcher inequality, which is the relevant geometric inequality associated with the minimization of the total inverse mean curvature under a volume constraint. We show that the symmetry between Aleksandrov's theorem and the HeintzeKarcher inequality breaks down when boundary conditions are imposed. Precisely, we deal with the variational behavior of the total inverse mean curvature for smooth curves in the halfplane, prescribing both the enclosed volume and a boundary condition. We characterize the existence of equilibrium configurations, and we discuss various notions of stability. As an application, we establish a local minimization property. This talk is based on a joint work with J. Pozuelo and G. Vianello. 17 dicembre 2025 ore 14:30 (Aula Fermi)

Workshop "Calculus of Variations and Free Boundary Problems: the VAREG edition"
by Giulia Bevilacqua 04 Dec '25

04 Dec '25

Care tutte, cari tutti, segnaliamo da parte degli organizzatori Giulia Bevilacqua, Filippo Paiano e Bozhidar Velichkov, l’evento "Calculus of Variations and Free Boundary Problems: the VAREG edition”. Il workshop si terrà martedì 9 dicembre con inizio alle 9.30, presso l'Aula Seminari Est del Dipartimento di Informatica (secondo piano). Entrando dall’ingresso del Dipartimento di Informatica (che sarà segnalato con un cartello indicante il convegno), seguendo le scale sulla destra, l’aula si trova al secondo piano (ci saranno dei cartelli per indicare la direzione dell’aula). Per info: http://www.velichkov.it/workshop-CVFBP-special.html. Segnaliamo inoltre che nella mattinata di mercoledì 10 dicembre, sempre nella stessa aula (a partire dalle 10:00), si terranno due seminari tenuti da Idriss Mazari-Fouquer (Université Paris-Dauphine) e Giacomo Colombo (ETH Zurich). Titoli e abstracts dei seminari si trovano in calce alla mail. A presto, Giulia Bevilacqua a nome degli organizzatori ________________________________ Dear all, on behalf of the organizers Giulia Bevilacqua, Filippo Paiano, and Bozhidar Velichkov, we announce the event "Calculus of Variations and Free Boundary Problems: the VAREG edition". The workshop will take place on Tuesday, December 9th starting at 9:30, in the Aula Seminari Est of the Department of Informatics (second floor). Directions: Entering through the main entrance of the Department of Informatics (which will be marked with a sign for the workshop), take the stairs on the right. The room is located on the second floor (there will be signs indicating the direction to the room). For info: http://www.velichkov.it/workshop-CVFBP-special.html. We also inform you that on the morning of Wednesday, December 10th, in the same room (starting at 10:00), two seminars will be held by Idriss Mazari-Fouquer (Université Paris-Dauphine) and Giacomo Colombo (ETH Zurich). Please find the titles and abstracts below. See you soon, Giulia Bevilacqua on behalf of the organizers ——————————————— Giacomo Colombo (ETH Zurich) Title: Generic regularity in obstacle-type problems. Abstract: I will talk about results in generic regularity in obstacle-type free boundary problems. I will explain the core ideas of their proofs focusing on generic regularity for the Stefan problem in 4+1 dimensions, and an application of these generic regularity results to β-models. Idriss Mazari-Fouquer (Université Paris-Dauphine) Title: Quantitative inequalities in optimal control theory and convergence of thresholding schemes Abstract: We will give an overview of recent progress in the study of quantitative inequalities for optimal control problems. In particular, we will show how they can be used to obtain convergence results for thresholding schemes, which are of great importance in the simulation of optimal control problems. This is a joint work with A. Chambolle and Y. Privat.
