Seminario Padova - Lucio Galeati
by alekos.cecchin＠unipd.it 13 Feb '26

13 Feb '26

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (28 Novembre) alle 14:30 in aula 2BC30 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Lucio Galeati (Università dell'Aquila) <https://sites.google.com/view/lucio-galeati-math/home> https://sites.google.com/view/lucio-galeati-math/home Title: Anomalous dissipation and anomalous regularization in the Kraichnan model of turbulence Date: November 28, 2025, at 14:30, 2BC30 Abstract: In the 60s Kraichnan proposed a synthetic model for passive scalar turbulence, consisting of a scalar advected by a random Gaussian velocity field, white in time and -Holder continuous in space. Despite its simplicity, this SPDE displays anomalous dissipation of energy, spontaneous stochasticity and intermittency, which are also expected for more realistic turbulent fluids. At the same time, solutions to the inviscid SPDE are unique and can be recovered by vanishing viscosity and mollification schemes. In this talk I will present some recent further understandings on this model: i) solutions to the transport equation with initial data display anomalous regularisation and almost gain Sobolev regularity , but not better; ii) solutions to the continuity equation starting from Dirac deltas instantaneously gain Lebesgue integrability, due to the diffusive behaviour of Lagrangian particle splitting, and their variance at small times grows like . Based on joint works with M. Maurelli, F. Grotto, U. Pappalettera and T. Drivas. Vi aspettiamo numerosi!

SPASS seminar: Giacomo Ascione
by Francesco Grotto 28 Nov '25

28 Nov '25

Dear Colleagues, We would like to invite you to the following SPASS seminars, *Fully nonlocal operators emerging from semi-Markov processes* by Giacomo Ascione (Scuola Superiore Meridionale), TUE 2.12.2025 at 14:00 CET in Sala Riunioni, Dipartimento di Matematica, UNIPI. A link for online participants will be shared on the website https://sites.google.com/unipi.it/spass Best, Francesco Grotto on behalf of the organizers ---------------------------------------------------------------- /Abstract: In the context of anomalous diffusions, time/space-nonlocal operators play a quite prominent role. For instance, the usual fractional Laplacian can be easily recognized as the generator of an isotropic stable Lèvy motion, that, still preserving the Markov property, represent a first (actually pure jump) example of anomalous diffusion, in the sense that the mean square displacement of the described particles (or, in terms of the process, its variance) is not linear in time (actually it is infinite). On the other hand, if we consider the heat equation with a fractional derivative operator in time, a stochastic representation of the solution of such an equation can be given in terms of a Brownian motion time-changed by means of the first passage time process of an independent stable subordinator. This process, however, clearly loses the Markov property, due to the addition of a further dependence on the current sojourn time. In both case, we are describing (at least in terms of the one-dimensional distributions) the behaviour of a time-changed Brownian motion, where the time-change is indeed independent of the process itself. The same can be done if we apply a time-change via an inverse subordinator to an independent isotropic stable Lèvy motion, (obtaining) uncoupled non-local operators in both time and space. However, if we remove the independence assumption, we cannot expect to get uncoupled behaviours in time and space. This is the case, for instance, of a Brownian motion time-changed first with an independent stable subordinator and then with its own inverse. As the second time-change is clearly dependent of the first one, we expect the two operators (in time and space) to be coupled in some way: precisely, in such a case, the Kolmogorov-type equation one gets is governed by a fractional power of the whole heat operator. In this talk, I will present some well-posedness results for fully nonlocal operators obtained by means of Bochner subordination of heat-like operators in terms of a family of semi-Markov processes obtained by means of non-independent time-changes. The general theory will be set in the framework of Feller semigroups on the space of continuous functions vanishing at infinity. Nevertheless, if there is time, a quite specific case (i.e., a Black-Sholes model for intraday options) that requires refined arguments will be discussed and the role of the regularity of the initial data will be addressed. Finally, we will stress the following expected result: despite the appearance of constancy intervals and the lack of Markov property, if we start from a Brownian motion the newly obtained process exhibits a normal diffusive behaviour, instead of an anomalous one./

Online seminar - Department of Economics - Ca' Foscari University of Venice
by Antonella Basso 27 Nov '25

27 Nov '25

Dear all, the Department of Economics of Ca' Foscari University of Venice organizes the following online seminar on*Friday, November 28 at 12:15 (ZOOM only)* by *Guglielmo Alessandro Visentin* (University of Reading) *The Financial Cost of Biodiversity Loss for SMEs *(joint with Lisa Schopohl and Simone Varotto) /Abstract: In this study, we investigate the impact of biodiversity loss on the performance of small and medium-sized enterprises (SMEs) in the United Kingdom and Ireland. Leveraging firms’ financial information and postcodes from Moody’s Bureau van Dijk and the Biodiversity Intactness Index – a geospatial dataset developed by the Natural History Museum – we geo-locate SMEs, quantify biodiversity loss in the area where firms operate, and assess their exposure to biodiversity-related risks over time. We then employ a fixed effects regression model to estimate the effect of biodiversity loss on firm performance. Our findings indicate that a one-standard-deviation decline in biodiversity leads to a statistically significant reduction in firm operating income by 0.59 percentage points. This impact is economically meaningful when benchmarked against the sample’s average operating income. Moreover, SMEs located in more ecologically degraded areas are found to be more exposed to biodiversity-related risks. We also provide evidence of the materiality of dependency risk, while transition risk appears to be non-material within the UK context. The results remain robust across various econometric specifications and when controlling for climate risk factors./ / / The Zoom link is: *https://unive.zoom.us/j/81355902934?pwd=4UWO6ugBkddwqj1v3RCbMNzPhOpIIh.1 ID riunione: 813 5590 2934 Passcode: dN548g */ / More information available here <https://www.unive.it/data/agenda/3/108966>/. / Best regards, Antonella Basso -- Antonella Basso Dipartimento di Economia Università Ca' Foscari Venezia Fondamenta S.
