Séminaire : On Regularization of Mirror Sweeping Process
29 septembre 2023 @ 11:00 – 12:00 – The Mirror Sweeping Process is a constrained differential Inclusion involving a normal cone to a moving set. In this talk, we present the well-posedness theory for this dynamical system under different sets of assumptions. We also discuss some applications to online optimization and possible extensions to other fields.
BPHZ theorem on regularity-integrability structures
28 septembre 2023 @ 10:45 – 11:45 – In the study of singular SPDEs, it has been a challenging problem to obtain a simple proof of a general probabilistic convergence result (BPHZ theorem). Differently from Chandra and Hairer’s Feynman diagram approach, Linares, Otto, Tempelmayr, and Tsatsoulis recently proposed an inductive proof based on the spectral gap inequality by using their multiindex language. Inspired […]

Sur les déformations des groupes de Lie semisimples
28 septembre 2023 @ 02:15 – 03:15 – Un groupe de Lie semisimple G peut être placé dans une famille de déformations qui aboutit dans le groupe de mouvements de Cartan. Cette idée provient de Mackey avec clarification par Higson et Afgoustidis. Si G est complexe, sa structure de Poisson-Lie permet une famille de déformations de $G$ dans des groupes quantiques découverts par […]
Probabilistic structures emerging from dormancy
27 septembre 2023 @ 10:45 – 11:45 – Dormancy is a complex trait that has evolved independently many times across the tree of life. In particular many micro-organisms can enter a reversible state of vanishing metabolic activity. The corresponding dormancy periods can range from a few hours to potentially thousands of years. Also, the dormancy transitioning mechanisms are highly diverse, including spontaneous dormancy […]
