UNIVERSITA' DI SALERNO Dipartimento di Matematica *AVVISO** DI SEMINARIO* Il Prof. *Thomas SIMON *(Université de Lille) terrà, *mercoledì 8 novembre, alle ore 15:00*, presso la Sala Riunioni dell'Edificio F2 (piano 1, stanza 36), un seminario dal titolo: *On Tsallis cumulative entropies* Gli interessati sono cordialmente invitati a partecipare, *Antonio Di Crescenzo* *Barbara Martinucci* *Alessandra Meoli**Serena Spina* Link su Teams: https://teams.microsoft.com/l/meetup-join/19%3a6hfHOOIVt89PyLIJDpqXis553z6p… * Abstract* We investigate the Tsallis cumulative entropy, an information measure recently introduced as a cumulative version of the classical Tsallis differential entropy. This functional is considered as a perturbation of the expected mean residual life via some power weight function. This point of view leads to the introduction of the dual cumulative Tsallis entropy and of two families of coherent risk measures generalizing those built on mean residual life. We characterize the finiteness of the cumulative Tsallis entropy in terms of Lp-spaces and show how they determine the underlying distribution. We also study the range of the Tsallis cumulative entropy under various constraints. In the symmetric case with finite variance, whereas the maximization of the Tsallis differential entropy gives rise to the classical q−Gaussian distribution which is a perturbation of the Gaussian distribution having a finite range or heavy tails, the maximization of the cumulative Tsallis entropy leads to an analogous perturbation of the Logistic distribution.

LTI@UniTO Seminar: Leonidas Barbopoulos | November 7, 2023 @ 12:00 - 13:15
by Luca Regis 03 Nov '23

03 Nov '23

Dear Colleagues, it is my pleasure to forward you the invitation to the following seminar organized by LTI@UniTO and CCA. The seminar can be attended online via zoom (link below). Best regards, Luca Regis <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/sh/SMK1E8tHeFuBlzkcYLDa5hFz9Ao6/rk…> LTI@Unito and Fondazione Collegio Carlo Alberto are pleased to invite you to the following seminar *November 7, 2023 | 12:00 - 13:15* *The Real Effects of Dark Trading* *Leonidas Barbopoulos (University of Edinburgh Business School)* *Abstract*. Up to 50% of trading in some stocks is in opaque off-market venues, prompting regulatory debate about dark trading. We analyze the real effects of dark trading and find that it positively impacts corporate investment decisions. In moderate amounts, it makes stock prices more informative, thereby helping managers learn from stock prices, and improving company performance. It also increases manager forecast accuracy and influences decisions during M&As. However, high levels can be harmful. We address identification through a quasi-natural experiment, instrumental variables, and Heckman selection models.

SPASS Seminar: Theresa Lange
by Francesco Grotto 03 Nov '23

03 Nov '23

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Regularization by noise of an averaged version of the Navier-Stokes equations* Theresa Lange (University of Bielefeld) The seminar will take place on TUE, 7.11.2023 at 14:00 CET in Aula Mancini, Scuola Normale Superiore, Pisa and streamed online at the link below (*please notice the unusual venue*). The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract: * *In [T16], the author constructs an averaged version of the deterministic three-dimensional Navier-Stokes equations (3D NSE) which experiences blow-up in finite time. In the last decades, various works have studied suitable perturbations of ill-posed deterministic PDEs in order to prevent or delay such behavior. A promising example is given by a particular choice of transport noise used in [FL21] in the context of the vorticity form of the 3D NSE, and in [FGL21] for more general models. In this talk, we analyze the model in [T16] in view of those two works and discuss the regularization skills of transport noise in the context of the averaged 3D NSE. This is joint work with Martina Hofmanová (U Bielefeld).* *References:* *[T16] T. Tao, Finite time blowup of an averaged three-dimensional Navier-Stokes equation.
