Padova Seminars in Probability and Finance - Benedikt Jahnel (WIAS, Berlin)
by Marco Formentin 13 Mar '22

13 Mar '22

Dear Colleagues, we would like to invite you to the following seminar that will take place on March 25 at 14.30. The seminar will be held online via the Zoom platform. The organizers, Alessandra Bianchi, Giorgia Callegaro, Marco Formentin _____________________________________________________ Speaker: Benedikt Jahnel (WIAS, Berlin)  Title: Phase transitions and large deviations for the Boolean model of continuum percolation for Cox point processes  MARCH 25 (Friday) - 14:30 Zoom link https://unipd.zoom.us/j/83753744114 (meeting ID 837 5374 4114), available also on the webpage https://www.math.unipd.it/~bianchi/seminari/ Abstract: In this talk, I consider the Boolean model with random radii based on Cox point processes, i.e., Poisson point processes in random environment. Under a condition of stabilization for the random environment, our results establish existence and non-existence of subcritical regimes for the size of the cluster at the origin in terms of volume, diameter and number of points, also including their moments. The second part of the talk will address rates of convergence of the percolation probability for the Cox--Boolean model with fixed radii in a variety of asymptotic regimes. This is based on joint work with Christian Hirsch, András Tóbiás and Élie Cali.

(PMS)^2 online talk: Valentina Cammarota
by Maurizia Rossi 13 Mar '22

13 Mar '22

Dear colleagues, we are happy to announce the following online talk: Speaker: *Valentina Cammarota* (Università di Roma La Sapienza) Title: *No repulsion between critical points for random plane wave and planar Gaussian random fields.* Abstract: Random plane wave is conjectured to be a universal model for high-energy eigenfunctions of the Laplace operator on generic compact Riemannian manifolds. This is known to be true on average. We discuss one of important geometric observable: critical points. We first compute one-point function for the critical point process, in particular we compute the expected number of critical points inside any open set. After that we compute the short-range asymptotic behaviour of the two-point function. This gives an unexpected result that the second factorial moment of the number of critical points in a small disc scales as the fourth power of the radius. Joint work with Dmitry Beliaev and Igor Wigman. Date and time: *Monday March 14, 17:30-18:30 (Rome time zone)*. Zoom link: https://us02web.zoom.us/j/84185018822?pwd=UE80NXJ2Z01GaWN3aTduMGVpeG9EQT09 ID riunione: *841 8501 8822* Passcode: *713253* This is a talk of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics* organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico and Milano-Statale.

Seminar in Statistics - CRISTINA BUTUCEA

12 Mar '22

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 18 Marzo 2022, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Cristina Butucea* (CREST, ENSAE IP Paris) Title: *Nonlinear functionals estimation under local differential privacy* Abstract: The concept of differential privacy provides a rigorous formalism to randomize data and quantify the amount of privacy. We consider i.i.d. individuals with outcomes distributed according to the common probability distribution P. This original data is further randomized using a privacy mechanism into observations that the statistician is allowed to use in order to recover information about the distribution P. We will consider local differential privacy where each sample from the original data is privatized on the user’s local machine before its release. We build privatized samples and nonparametric estimation methods of nonlinear functionals of the probability density and prove their optimality. We show that for the estimation of a quadratic functional, interactive procedures that use previously released private data are faster than the non interactive ones. In both cases we show how to produce privacy mechanisms and estimators adaptive to (free of) the smoothness of the underlying density. We extend these results to non smooth functionals of the density. This is based on joint work with A. Rohde, L. Steinberger and Y. Issartel. ------------------------------------------------ In ottemperanza alle norme anti Covid, per partecipare in presenza è necessario prenotarsi tramite il seguente form online: https://forms.gle/s6n5Z8QwNYp7fypw7 Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/88303761211?pwd=MzFhOThna1B5WWFqWVNySEVMcEVMdz09> Meeting ID: 883 0376 1211 Passcode: 493770 Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats Cordiali saluti, Pierpaolo De Blasi -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/> -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 18 Marzo 2022, alle ore 11.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Peter Tankov* (CREST, ENSAE IP Paris) Title: *Mean-field games: the linear programming approach* Abstract: We will review the linear programming approach to mean-field games, developed by the author in a series of papers. Mean-field games are games with a large number of identical small agents and symmetric interactions, which have found many applications in finance and economics. The linear programming approach is a relaxation technique, which allows to prove existence results under weak assumptions, and lends itself well to numerical implementation. We will present an application of the approach to a model of energy markets and discuss the « linear programming fictitious play » algorithm for approximating the equilibrium. ------------------------------------------------ In ottemperanza alle norme anti Covid, per partecipare in presenza è necessario prenotarsi tramite il seguente form online: https://forms.gle/Bmxgd6w2wxtMT6aT9 Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/88303761211?pwd=MzFhOThna1B5WWFqWVNySEVMcEVMdz09> Meeting ID: 883 0376 1211 Passcode: 493770 Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats Cordiali saluti, Pierpaolo De Blasi -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Fwd: Oberwolfach Arbeitsgemeinschaft on Quantitative Stochastic Homogenization
by Faggionato, Alessandra 08 Mar '22

08 Mar '22

Buongiorno, Antoine Gloria mi ha pregata di pubblicizzare il gruppo di lavoro ``Oberwolfach Arbeitsgemeinschaft'' su ``Quantitative Stochastic Homogenization'' organizzata da A. Gloria, F.Otto ad Oberwolfach nella settimana October 16th - October 22nd 2022. Sotto trovate varie informazioni e al link anche una descrizione e un programma dettagliati, prese dalla mail che mi ha inviato. Grazie dell'attenzione Saluti Alessandra %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% The Arbeitsgemeinschaft is an old Oberwolfach institution, started by Faltings and Deninger. It is a reading group with presentations, organized like a students' seminar. The target group are mathematicians of all academic age that are interested in an efficient introduction into a timely topic, with an own active participation. As opposed to workshops, people apply to participate. Incidentally, at the end of each Arbeitsgemeinschaft, the participants discuss topics for next year. For a long time, there has been just a single strand. Recently, Oberwolfach decided to widen to three strands, of which Martin Hairer, Peter Scholze, and Andreas Thom are in charge. The idea is that Martin's strand will be targeted towards more applied topics. Martin asked Felix and me to organize the first event on this topic. (Fifteen years ago, Theo Sturm organized a week on Optimal Transportation). It would be great if you could advertise the event; perhaps there are people in your environment that are interested. More details and the list of topics plus material for the talks are under https://www.mfo.de/occasion/2242/www_view Thank you and best wishes, Antoine -- ************************************************* Prof. Alessandra Faggionato http://www1.mat.uniroma1.it/~faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 5, Phone (0039) 06 49913252 *************************************************
