Buongiorno il seminario di Lorenzo Dello Schiavo precedentemente annunciato sarà anticipato alle ore 13.45. Sotto l'annuncio aggiornato. Grazie Alessandra %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Martedi' 7 Maggio, ore 13:45, Aula di Consiglio, Dip. Matematica, La Sapienza Speaker: Lorenzo Dello Schiavo (Università di Bonn) Titolo: The Dirichlet-Ferguson diffusion Abstract: We define, via Dirichlet forms’ theory, a geometric diffusion process on the L^2-Wasserstein space over a closed Riemannian manifold. The process is associated with the Dirichlet form induced by the L^2-Wasserstein gradient and by the Dirichlet-Ferguson random measure with intensity the Riemannian volume measure on the base manifold. We discuss the closability of the form via an integration-by-parts formula, which allows explicit computations for the generator and a specification of the process via a measure-valued SPDE. We comment how the construction is related to previous work of von Renesse—Sturm on the Wasserstein Diffusion and of Konarovskyi—von Renesse on the Modified Massive Arratia Flow. -- ************************************************* 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 *************************************************

International Conference in Venice - CALL FOR PAPERS
by Monica Billio 01 May '19

01 May '19

CREDIT2019 <http://www.greta.it/credit/credit2019/credit2019.htm> *GRETA Associati* (Venice, Italy), *European DataWarehouse* (Frankfurt am Main, Germany), *Intesa Sanpaolo* (Milan, Italy) and *S&P Global Market Intelligence* (London, UK) are co-sponsors of a Conference to be held in Venice on September 26-27, 2019. The objective of the Conference is to bring together academics, practitioners and Ph.D. students working in the area of risk management. The conference will provide an opportunity for participants engaged in research at the forefront of this area to discuss both the causes and implications of recent financial and atmospheric events and may, in turn, suggest fruitful directions for future research. The Conference, organised under the auspices of the *Department of Economics of the University Ca’ Foscari of Venice*, *ABI - Italian Banking Association*, *AIAF - Associazione Italiana per l'Analisi Finanziaria* (Milan, Italy) and the *Joint Research Center, European Commission* (Ispra, Italy), is the *eighteenth *of a series dedicated to various aspects of credit risk. //The adoption of the Paris Agreement on climate change and the UN 2030 Agenda for Sustainable Development marks a historical international commitment to the objective of a more sustainable economy and society. How to mobilise the necessary financing for green and sustainable investments is thus a primary need. // //Meanwhile, Regulators are discussing about a green-supporting or a brown-penalising factor since they want to make sure financial institutions are prepared. It is to find the way to support sustainable investments but it is primarily a discussion about credit risk.// //The banking and insurance industries and more in general the financial sector has to develop new asset management strategies and to adjust their credit allocation practices to cope with these new challenges and take advantage of the new opportunities. All these changes call for a substantial amount of research to improve the knowledge of the mechanisms at play and to design adapted policy tools. ////////// The organizers encourage submissions of papers on any topic within the overall theme of the conference and in the following areas in particular: * Analysis of climate change effects on companies’ creditworthiness, in terms of risk exposure and possible loss of business continuity; understanding on how to integrate the environmental risk and opportunities of banks’ or insurers’ counterparties in the credit process * Development of metrics for climate-related financial risks and investments opportunities; definition of an EU environmental and climate change (ECC) risk categorising system by economic sectors/sub-sectors for ECC screening to provide a sound and reliable basis for setting high-level policies for credit protection and allocation * Analysis of the climate change impact on the insurance sector and on the development of non-life and reinsurance products for the corporate and retail segments Analysis of climate-aligned developments in the financial markets (e.g. green bonds) and opportunities for financial institutions in fostering the low-carbon transition * Transmission channels of climate-related shocks from the real economy to financial institutions’ portfolios and amplification mechanisms of climate-related shocks through credit chains * Assessment of the potential impact of green financial policies, including climate-aligned monetary policies and macroprudential regulation * Big data and artificial intelligence to assess and manage the corporate exposures to climate change factors. The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Robert Engle *(New York University, Stern Business School), *Andreas Hoepner* (University College Dublin), *Irene Monasterolo* (Wirtschaftsuniversität Wien, Vienna) and *Til Schuermann *(Oliver Wyman, New York). The Conference will also feature a panel discussion on researchers', practitioners' and policy makers’ views of the major outstanding problems.

SEMINARIO Fisica Matematica Eveliina Peltola Universita' di Ginevra Titolo: Crossing probabilities of multiple Ising interfaces Giovedi' 09 Maggio 2019 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 311 Abstract I discuss crossing probabilities of multiple interfaces in the critical Ising model with alternating boundary conditions. In the scaling limit, they are conformally invariant expressions given by so-called pure partition functions of multiple SLE(kappa) with kappa=3. I also describe analogous results for critical percolation and the Gaussian free field.

Seminario di Jacques Franchi a Roma
by Anna Vidotto 29 Apr '19

29 Apr '19

Dear all, I would like to announce the following talk that will be held on Tuesday, May 7th 2019, at 4:30 PM in Aula Dal Passo of the Department of Mathematics, University of Rome Tor Vergata. Speaker: Jacques Franchi (I.R.M.A. Strasbourg) Title: Small time equivalents for the density of a planar quadratic Langevin diffusion Abstract: Exact small time equivalents for the density of the (heat kernel) semi-group, with a control of the error term, are obtained for a quadratic planar analogue of the Langevin diffusion, which is strictly hypoelliptic and non-Gaussian, hence of a different nature from the known Riemannian, sub-Riemannian and linear-Gaussian cases. Namely I consider the density p_t of X_t := ( B_t , \int_0^t B_s^2 ds ), where B_t is real Brownian, and I obtain the asymptotic behaviours, as t --> 0, of p_t(0,(w,y)) and p_t(0,(w,ty)), which both can be seen as natural extensions beyond the degenerate Langevin-Gaussian framework. The result for the scaled regime is the first such one in a non-Gaussian strictly hypoelliptic framework. The method is half-probabilistic half-analytic.

Mini-course announcement: Stochastic control and mean-field games [L.Campi @Dept. Comp. Science - UniVr]
by Luca di persio 28 Apr '19

28 Apr '19

The Dept. of Comp. Science, College of Mathematics [ UniVr ] : https://goo.gl/maps/yeKWo3vri8PkHjUm9 will host the following mini-course *Title*: Stochastic control and mean-field games [ 2 ECTS ] which will be given by prof. Luciano Campi [LSE - London] *Stochastic control and mean-field games* In this mini-course we will give a short introduction of stochastic control problems and games, especially in view to applications in economics and finance such as - but not limited to - portfolio optimization. Two main approaches will be discussed: dynamic programming principle via PDEs (Partial Differential Equations), Pontryagin maximum principle via BSDEs (Backward Stochastic Differential Equations). Moreover, an application to the latter method to the very popular class of mean-field games (MFGs) will be presented as well together with some relevant applications to study strategic interaction among economic agents, such as banks and investors. Other applications of MFGs to, for instance, energy markets and crowd dynamics, will be also discussed if time allows. The list of topics will be: (i) Stochastic control: formulation of the problem with examples. (ii) Dynamic programming principle and Hamilton-Jacobi-Bellman PDE. (iii) Pontryagin stochastic maximum principle and BSDEs. (iv) Mean-field games: characterization of Nash equilibria and applications. *Main references*: • Carmona, R., Delarue, F. (2018).
