Seminar of Francesco Morandin and Alessandro Montagnani, Padova 18/02/2020
by barbato＠math.unipd.it 14 Feb '20

14 Feb '20

Dear Colleagues, we would like to invite you to the following Probability seminar that will take place at the Department of Mathematics of Padova, on February 18. Speaker: Francesco Morandin Title: Turbulence, shell models and critical exponents for dissipation Abstract: Shell models of turbulence are nonlinear dynamical systems inspired by fluid dynamics. They are idealized and simplified, but tailored to exhibit the same energy cascade behaviour of three dimensional Euler and Navier-Stokes equations. A typical feature of these models is in fact anomalous dissipation of energy, which in finite time "escapes" to infinity, yielding a blow-up and instantaneous loss in regularity. A dissipative term corresponding to viscosity can recover regularity, for some of these models, but in total generality one needs hyper-dissipation, with an exponent larger than the physical one. Recent results hint that in the more refined framework of tree (hierarchical) models the required exponent may be actually lower. Speaker: Alessandro Montagnani Title: A stationary solution for turbulence shell models. Abstract The focus of the talk is to study well-posedness, with respect to generic Gaussian distributed initial data, in turbulence shell models. In the of state-of-the-art results we have existence of solution for any finite energy initial conditions. Here we show the generic existence of solutions with respect to initial data distributed as Gaussian invariant measures, in "mixed" dyadic and tree-like shell models, extending the classical deterministic results. The existence is given thanks to compactness argument and techniques similar to the ones used by Albeverio and Cruzeiro for Euler equation (and more recently with a different approach by F. Flandoli), adapted to our model. Uniqueness is not provided, and the natural oscillating behaviour of the solutions obtained may suggests that it doesn't hold at all All of you are very welcome. Best regards, David Barbato

PhD Course, Tor Vergata (Matematica), Paolo Pigato
by Claudio Macci 13 Feb '20

13 Feb '20

Department of Mathematics, Univ. Roma Tor Vergata PhD Course held by Paolo Pigato (10 hours) Title: Fractional Brownian motion and non-Markovian modeling Schedule: March 03, 2020; h. 14-16. Room: Aula D'Antoni March 05, 2020; h. 14-17. Room: Aula D'Antoni March 10, 2020; h. 14-16. Room: Aula De Blasi March 12, 2020; h. 14-17. Room: Aula D'Antoni Abstract. In several applications of stochastic analysis (financial engineering, telecommunication networks, ...), it is desirable to model real-world quantities which are non-Markovian, for example because the noise process exhibits slowly decaying auto-correlations and long memory. In this course we will focus on fractional Brownian motion, a prototypical example of non-Markovian process. Such process is a generalisation of Brownian motion with Holder regularity possibly different than 1/2 and it is not a martingale. We will consider large deviations problems, simulation methods and some examples of application. Some other details can be found here: http://www.mat.uniroma2.it/~macci/corso-dottorato-pigato.htm Best regards. Claudio Macci.

BAYSM 2020: Announcement on coronavirus
by Federico Camerlenghi 13 Feb '20

13 Feb '20

Dear all, as you may already be aware, there is a recent coronavirus epidemic going around in China, which may have raised concerns in attending the BAYSM 2020 meeting in China late June https://baysm2020.uconn.edu/ . As a satellite meeting of the 2020 ISBA World Meeting (Kunming, China, June 29-July 03), we would like to cite the email that ISBA Program Council just sent to ISBA members to address the coronavirus concerns and ISBA World Meeting in China: "We are keeping a close eye on the development. While at this point we are cautiously optimistic that the epidemic will not last till June, both as a result of the extraordinary measure that China is taking to contain the spread, and as cold-like coronaviruses generally don't spread effectively as temperature rises in spring. However, we want to stay cautious and keep options open, and will take the necessary actions to ensure the health and safety of our community." We are holding the same position as the ISBA Program Council and will keep you all updated of any changes in the plan of the meeting. Particularly, if the epidemic is not contained in the next couple of months, and thus the community participating in the meeting will be subject to health risk, we will consider alternatives such as postponing the BaYSM Meeting. For now, we have decided to extend the early registration deadline as follows. Deadline for submissions: May 1 2020 23:59 CST End of review process: May 23 2020 Early registration: June 01 2020 Late registration: June 15 2020 Thank you for your support of our BaYSM Meeting. We hope that the epidemic will be over soon and we will see you all in Kunming at the BaYSM this June. Best Regards, On behalf of the organizing committee Federico Camerlenghi -- Federico Camerlenghi Department of Economics, Management and Statistics University of Milano Bicocca, Milano, Italy. web-page: https://www.unimib.it/federico-camerlenghi

Seminar of Nicola Secomandi, Padova, Friday 21

*** Apologies for cross-posting *** Dear Colleagues, we would like to invite you to the following Probability seminar that will take place at the Department of Mathematics, University of Padova (via Trieste, 63), on February 21 h. 15.30 room 1BC/45. -------------------------------------------------- NICOLA SECOMANDI Tepper School of Business, Carnegie Mellon University Quadratic Hedging and Optimization of Option Exercise Policies in Incomplete Markets and Discrete Time Abstract: This paper extends quadratic hedging from European to Bermudan options in discrete time when markets are incomplete and investigates its use for supporting exercise policy optimization. The key idea is to construct date specific approximate replicating portfolios. Hedging any given exercise policy can be done by solving a collection of stochastic dynamic programs. Optimizing the exercise policy based on the resulting martingale measure requires care. If this measure is risk neutral (RN), the value of an optimal such policy, which can be obtained by augmenting the hedging model with an exercise policy optimization step, is a no arbitrage one. Otherwise this approach must be refined by imposing time consistency on exercise policies, although the value of the resulting exercise policy may not be arbitrage free. Following the common pragmatic strategy of specifying quadratic hedging under an RN measure, e.g., one calibrated to market prices, avoids these issues. In particular, it provides a simple hedging policy with immediate practical applicability and is equivalent to exercise policy optimization under RN valuation, thus complementing it with a consistent hedging policy. A simple numerical example shows that this procedure generates effective hedging policies.
