SUMMARY:Estimation of group action via non-commutative Fourier transform with special functions
DESCRIPTION:In this seminar\, we will discuss the estimation of group action using the non-commutative Fourier transform. \nWe’ll explore an interesting relationship between the non-commutative Fourier transform and this estimation problem. \nNext\, we’ll optimize our estimation method by leveraging this connection under various conditions\, including energy constraints. \nFinally\, we’ll apply the obtained results to uncertainty relations related to compact groups. \nThroughout this discussion\, we’ll highlight the significance of several special functions in this topic.

SUMMARY:Regularization by noise and approximations of singular kinetic SDEs
DESCRIPTION:Regularisation by noise in the context of stochastic differential equations (SDEs) with coefficients of low regularity\, known as singular SDEs\, refers to the beneficial effect produced by noise so that the singularity from the coefficients is smoothed out yielding well-behaved equations. Kinetic SDEs\, also sometimes called second order SDEs\, as one typical type of stochastic Hamiltonian systems\, describe the motion of a particle perturbed by some random external force. The difference of comparing it with usual SDEs is that the noise of the space position vanishes and only appears in the direction of velocity\, hence less noise gets involved in the system. In this talk we will discuss about the regularization effect by the degenerate noise for the singular kinetic SDEs from numerical approximation and also particles approximation view point.

SUMMARY:Robust construction of the high-dimensional incipient infinite cluster
DESCRIPTION:In Bernoulli percolation\, the incipient infinite cluster (IIC) is a version of the “open cluster of the origin at criticality conditioned to be infinite”. Since this event should have probability 0 on Zd\, the IIC is constructed via a limiting procedure. For d > 6\, several constructions have been given and shown to produce the same object\, but many natural limiting procedures remain unexplored. For instance\, it is an open question whether conditioning on {0 is connected to the boundary of [-n\, n]d} produces the IIC as n tends to infinity. We answer this question in the affirmative as a corollary of our theorem\, which roughly says “conditioning on any long open connection produces the IIC”\, and whose proof does not directly use lace expansion analysis.

SUMMARY:A duality method for mean-field limits with singular interactions
DESCRIPTION:We introduce a new approach to justify mean-field limits for first- and second-order particle systems with singular interactions. It is based on a duality approach combined with the analysis of linearized dual correlations\, and it allows to cover for the first time arbitrary square-integrable interaction forces at possibly vanishing temperature. This is joint work with D.Bresch and P.E.Jabin.
