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.

LTI@UniTO Webinar in Finance: Sohnke Bartram (Warwick Business School) 03.06 h.15
by Luca Regis 04 Jun '20

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 3rd at 3 pm via Zoom. Please register here https://ltiwebinar3june.eventbrite.it/ to get the Zoom link. Speaker: Sohnke Bartram (Warwick Business School) Title: "Currency Anomalies" || |*Abstract *| | This paper is the first to study the cross-section of currency anomalies to explore alternative explanations for their existence. Using real-time data, currency anomalies are profitable during in-sample and out-of-sample periods, both before and after transaction costs, but trading profits decrease substantially after the publication of the underlying academic research. The decline is greater for anomalies with larger in-sample profits and lower arbitrage costs, and signal ranks and performance decay quickly, suggesting that currency anomalies reflect mispricing rather than compensation for risk or statistical bias. Mispricing is systematically related to mistakes and changes in analysts’ currency forecasts. In particular, analysts expect anomaly payoffs that are too low compared with actual anomaly profits. However, analysts update their forecasts to incorporate lagged anomaly information. These results are consistent with a behavioral explanation for currency anomalies. | -- Luca Regis Associate Professor Department of Economics and Statistics (ESOMAS) University of Torino sites.google.com/view/lucaregis Office: +39 011 670 6065 www.carloalberto.org/lti

Probability Webminar: Alberto Chiarini (TU Eindhoven) [Padova 12/06, 15.00]
by alessandra bianchi 03 Jun '20

03 Jun '20

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on June 12 at 15 by the zoom platform. ________________________________________________________ Speaker: Alberto Chiarini (TU Eindhoven) Title: Entropic repulsion for the occupation-time field of random interlacements by disconnection 12 JUNE (Friday) - 15:00 - zoom link: TBA The link and password to access the seminar will be available at the following webpage https://www.math.unipd.it/~bianchi/seminari/ Abstract: The model of random interlacements was introduced in 2007 by A.-S. Sznitman, motivated by questions about the disconnection of discrete cylinders or tori by the trace of simple random walk. Since then, it has gained popularity among probabilists due to its percolative properties and also because of its connections to the free field. Random interlacements on transient graphs can be constructed as a Poisson point process of doubly infinite trajectories. After reviewing this model, we will focus on the rare event that these trajectories disconnect a macroscopic body from infinity, in the strongly percolative regime. We will ask the following question: What is the most efficient way for random interlacements to enforce such disconnection? In other words, how do the trajectories of random interlacements look like conditionally on disconnection? -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

Students and researchers in Mathematics at GSSI are encouraged to interact with other scientific communities. At GSSI, we believe that the interdisciplinary endeavor is the most effective way to do science and benefit society. Mathematical models are ubiquitous in physics, engineering, information theory, social and life sciences, as they provide a formidable framework to describe the time evolution of deterministic, stochastic and complex systems, which is one of the main goals at GSSI. Within the PhD program in Mathematics in Natural, Social and Life Sciences a priority has been established on mathematical modeling, both towards the traditional areas of application, such as Physics or Engineering, and towards emerging issues in Biology and in the Social Sciences. GSSI mathematics researchers are interested in tackling many problems with complementary perspectives and methods. The area of Mathematics is characterized by four large macro-sectors: Applied Partial Differential Equations, Stochastic Analysis, Numerical methods and Continuum Mechanics modeling. Within these sectors there is a shared interest in problems related to fluid dynamics, quantum mechanics, statistical mechanics and also its applications to data science. Important ideas of classical analysis, probability theory, mathematical physics and theoretical physics are used also for less traditional applications. Numerical linear algebra and numerical optimization help to design new models and accompanying numerical algorithms for applications in data mining, machine learning and network science. Continuum mechanics models, computational methods in fluid dynamics are used not only in their traditional field at the boundary between applied mathematics and theoretical engineering, but also in nonconventional problems like modeling the full heart function.
