Webinar Fabio Moneta (U. Ottawa) 17.06 h. 15 - LTI@UniTO Webinars in Finance

Dear Colleagues, LTI@UniTO (www.carloalberto.org/lti) and Collegio Carlo Alberto are pleased to invite you to the following seminar in Quantitative Finance, that will take place on June 17th at 3 pm CET via Zoom. Please register here: https://www.eventbrite.it/e/biglietti-holding-horizon-a-new-measure-of-acti… to get the Zoom link to join the webinar. /Speaker/: Fabio Moneta <https://telfer.uottawa.ca/en/directory/professors/moneta-fabio/> (University of Ottawa) Title: Holding horizon: a new measure of active investment management Abstract: This paper proposes a new holding horizon (HH) measure of active management and examines the relation between horizon and manager skill. Our HH measure identifies, in the cross-section, funds with higher future long-term alphas, while reported turnover identifies, in the time-series, when a particular fund is likely to exhibit a higher short-run alpha. The superior long-term performance of long-horizon funds is due to their selection of stocks with strong long-run fundamentals. Moreover, stocks largely held by long-horizon funds outperform stocks largely held by short-horizon funds by 2.7%-3.5% per year, adjusted for risk, over the following five-year period. We hope you will be able to join us!

If interested, please subscribe by https://docs.google.com/forms/d/e/1FAIpQLSfDWIEYewlpF_SWEeVV8DaTrzbftSTST8K… UNIVAQ RANDOM TALKS 5 Thursday June 18th 11:00 a.m. - ZOOM Videoconference platform Prof. Arturo Kohatsu-Higa Department of Mathematical Sciences Ritsumeikan University UPPER BOUNDS FOR THE JOINT DENSITY OF A STABLE PROCESS AND ITS MAXIMUM Abstract: In this article, we obtain integration by parts formulas for the joint law of a stable process and its maximum. The argument is based on a multi-level representation for the joint law which uses the theory of convex majorants for stable processes and the Chambers-Mallows-Stuck representation for stable random variables. As applications, we obtain regularity results for the joint law and upper bounds for the density and its space derivatives. Everybody is welcome, please subscribe by the following form The day of the seminar, participants will receive an invitation by e-mail (max. 100 participants)

---------- Forwarded message --------- Da: Andreas Kyprianou <ak257(a)bath.ac.uk> Date: mer 10 giu 2020 alle ore 08:57 Subject: [owps] One World Probability Seminar Thursday 11th June 2020 To: <owps(a)lists.bath.ac.uk> One World Probability Seminar Thursday 11th June 2020: Tomorrow we will have a double talk on "A new point of view on topological phase transitions“. The first talk will be more introductory and accessible for a large audience. ------------------------------------------------------------ 15.00 CEST: Christophe Garban (Lyon) 16.00 CEST: Avelio Sepúlveda (Lyon) Abstract: Topological phase transitions were discovered by Berezinskii-Kosterlitz- Thouless in the 70's. They describe intriguing phase transitions for classical spins systems such as the plane rotator model (or XY model). Part 1 : General introduction on the topological phase transitions. Without assuming any a priori background, we will discuss how this phase transition arises in cases such as : - the XY model (spins on Z^2 with values in the unit circle) - the integer-valued Gaussian Free Field - Abelian Yang-Mills on Z^4 We will also discuss some of the main contributions of Fröhlich and Spencer to this theory. Part 2 : A statistical reconstruction problem. We will connect topological phase transitions to a statistical reconstruction problem concerning the Gaussian Free Field and will show that the feasibility of the reconstruction undergoes a KT transition. The talks will be based mostly on the preprint: https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Farxiv.org… ------------------------------------------------------------ Please keep in mind that we are working with Central European summer time. As always, the Zoom-room link will appear on the OWPS seminar webpage: https://eur01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.owprob… But you can also link to it directly by clicking this link tomorrow: https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fus02web.z… Meeting-ID: 876 7251 4177 Please feel free to circulate this email.

********************************************************************* WEBINAR DI PROBABILITÀ E STATISTICA MATEMATICA DIPARTIMENTO DI MATEMATICA "G. PEANO" UNIVERSITÀ DEGLI STUDI DI TORINO ********************************************************************* Martedì 23 Giugno 2020 alle ore 15:00 Il Prof. Isaac Meilijson (Tel Aviv University) terrà un seminario sulla piattaforma webex Collegamento riunione: https://unito.webex.com/unito/j.php?MTID=m28a1e666a170497b27a0d1e4d8772ff2 Password:ParolaRiunione Title: Random time transformation analysis of Covid19 2020 Speaker: Isaac Meilijson, Tel Aviv University Abstract: The SIR epidemiological equations model new affected and removed cases as roughly proportional to the current number of infected cases. The present report adopts an alternative that has been considered in the literature, in which the number of new affected cases is proportional to the α<1 power of the number of infected cases. After arguing that α=1 models exponential growth while α<1 models polynomial or linear growth, a simple method for parameter estimation in differential equations subject to noise, the random-time transformation RTT of Bassan, Meilijson, Marcus and Talpaz 1997, will be reviewed and applied to fit α and the other parameters in an attempt to settle the question as to the nature of Covid19. Joint work with Nitay Alon. Tutti gli interessati sono invitati a partecipare.
