Statistics Seminars 2019 Giovedì 28 febbraio 2019 ore 16 Aula seminari - Dipartimento di Scienze Statistiche, I piano "Density and tube estimates for diffusion processes under Hormander-type conditions" Dr. Paolo Pigato, Weierstrass Institute for Applied Analysis and Stochastics, Berlino Abstract:"We recall some classic results on the regularity of solutions of stochastic differential equations. Then we consider two specific diffusion processes satisfying hypoellipticity conditions of Hormander type. Using Malliavin Calculus techniques recently developed to deal with degenerate problems, we find estimates for the density of the law of the solution, which we use to prove exponential bounds for the probability that the diffusion remains in a small tube, around a deterministic path, up to a given time. We then present some work in progress on asymptotic sharp estimates for the density and its derivatives for a similar, higher dimensional system."

de Finetti risk seminar - February 2019
by Emanuela Rosazza 13 Feb '19

13 Feb '19

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Jocelyne Bion-Nadal Ecole Polytechnique, Paris Title: Fully-Dynamic risk-indifference pricing Abstract: We propose a dynamic risk-indifference pricing evaluation derived from a fully-dynamic risk- measure on Lp-spaces. The concept of fully-dynamic risk-measures offers the possibility of changing the risk perspectives over time. It ts well the study of both short and long term investments. Dynamic risk-indifference pricing is an alternative to utility-indifference pricing. In the case p = +infinity, we prove that risk indifference pricing provides a proper convex price system. On the contrary, for p < infinity, it turns out that the domain of the risk-indifference pricing operator is not the whole Lp(Ft), not even a vector space. Therefore we propose a new framework. We prove Fatou property and time-consistency and we obtain a represen- tation result. LOCATION: The seminar will be held on Wednesday, February 20, at 18.00, Aula Chisini, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano.

seminario a Pavia - 19 febbraio 2019

12 Feb '19

ANNUNCIO di SEMINARIO Martedì 19 febbraio 2019 la prof. Hakima Bessaih (Wyoming) terrà un seminario presso l'aula Beltrami del Dipartimento di Matematica - Pavia; inizio previsto per le ore 14:00 precise. Tutti gli interessati sono invitati a partecipare. *Title*: Numerical schemes for the 2d Stochastic Navier-Stokes equations: Strong rate of convergence. *Abstract*: We consider a time discretization scheme of Euler type for the 2d stochastic Navier-Stokes equations on the torus. We prove a mean square rate of convergence. This refines previous results established with a rate of convergence in probability only. Using exponential moment estimates of the solution of the Navier-Stokes equations and a convergence of a localized scheme, we can prove strong convergence of fully implicit and semi-implicit time Euler discretization and also a splitting scheme. The speed of convergence depends on the diffusion coefficient and the viscosity parameter.

Seminari prof. Popovici a Varese

con la presente chiedo che vengano diffusi mediante la lista random gli avvisi relativi a tre seminari che il prof. Nicolae Popovici (Department of Mathematics - Faculty of Mathematics and Computer Science - Babes-Bolyai University – Cluj-Napoca, Romania) terrà presso il Dipartimento di Economia dell'Insubria. Si allegano anche le locandine. Grazie mille cordiali saluti enrico moretto *** Seminar announcement: Nicolae Popovici on a general local-global extremality principle in vector optimization On February 13th, 2019, 15.00-16.00, Prof. Nicolae Popovici (Department of Mathematics - Faculty of Mathematics and Computer Science - Babes-Bolyai University – Cluj-Napoca, Romania) will give a talk on “A general local-global extremality principle in vector optimization” (joint with Ovidiu Bagdasar, University of Derby, UK) Abstract It is known that any local minimal point of a semistrictly quasiconvex real-valued function is a global minimal point; also, any local maximal point of an explicitly quasiconvex real-valued function is a global minimal point, provided that it belongs to the intrinsic core of the function's domain. We have shown that these local min - global min and local max - global min type properties can be extended and unified by a general local-global extremality principle for generalized convex vector-valued functions with respect to two proper subsets of the outcome space. Keywords: unified vector optimization; generalize convex functions. Seminar announcement: Nicolae Popovici on new algorithms for solving discrete vector optimization problems On February 14th, 2019, 15.00-16.00, Prof. Nicolae Popovici (Department of Mathematics - Faculty of Mathematics and Computer Science - Babes-Bolyai University – Cluj-Napoca, Romania) will give a talk on “New algorithms for solving discrete vector optimization problems” (joint with Christian Guenther, Martin-Luther University of Halle-Wittenberg, Germany) Abstract We present some new Graef-Younes type algorithms for solving discrete vector optimization problems. In order to determine all minimal elements of a finite set with respect to an ordering cone, the original approach proposed by Jahn in 2006 (known as the Jahn-Graef-Younes method) consists of a forward iteration (Graef-Younes method), followed by a backward iteration. Our methods involve additional sorting procedures based on scalar cone-monotone functions. Keywords: discrete vector optimization; cone-monotone scalarization functions. Seminar announcement: Nicolae Popovici on a new algorithm for solving planar multiobjective location problems involving the Manhattan norm On February 15th, 2019, 11.00-12.00, Prof. Nicolae Popovici (Department of Mathematics - Faculty of Mathematics and Computer Science - Babes-Bolyai University – Cluj-Napoca, Romania) will give a talk on “New algorithms for solving discrete vector optimization problems” (joint with Shabagh Alzorba, Christian Guenther and Christiane Tammer, Martin-Luther University of Halle-Wittenberg, Germany) Abstract We study unconstrained planar multiobjective location problems, where distances between points are defined by means of the Manhattan norm. By eliminating the nonessential objectives we develop an effective algorithm for generating the whole set of efficient solutions as the union of a special family of rectangles and line segments. Keywords: location problems; Fermat-Weber type problems; Matlab algorithms.
