Dear all, on* Thursday 27th November* the following seminars will be held at the *Department of Statistical Sciences, Sapienza University*: *Time: 14:30* *Speaker: Lorenzo Cristofaro (University of Luxembourg)* *Title: *A novel p-Poincaré inequality and a multiplication formula *Abstract:* We show a novel family of p-Poincaré inequalities for almost surely finite random variables (p ∈ [1, 2]). Regarding the case of multiple Wiener-Ito integrals, our results yield general multiplication formulae on the Poisson space under minimal conditions, naturally expressed in terms of diagrams and/or contraction operators. *Time: 15:15* *Speaker: Wolfgang Bock (Linnaeus University, Vaxjo, Sweden)* *Title: *The characterization of Malliavin-Watababe-Sobolev spaces via the Bargmann-Segal Space *Abstract: *The characterization theorem and its corollaries set the foundation of the success of white noise analysis in the recent 30 years. On different occasions the fathers of the characterization J. Potthoff and L. Streit were asked by P. Malliavin and P.-A. Meyer if such a characterization is also possible for the Mallliavin-Watanabe Sobolev spaces. In this talk we present how we closed this gap and give a characterization of the Mallliavin-Watanabe Sobolev spaces with the help of the Bargmann-Segal transform. The characterization can also be generalized to the non-Gaussian setting. Examples will showcase the regularity of different objects. It will be possible to attend them in presence in *Room n.24*, Building CU002, p.le A.Moro 5, Rome (4th floor) and *online* at this link <https://uniroma1.zoom.us/j/84380852385?pwd=RDBrcVdvelRMM0VmczlXYWgwL2pPZz09> Best regards, Luisa *************************************************************** Luisa Beghin Dipartimento di Scienze Statistiche Fac.
