Dear Colleagues, we would like to invite you to the following seminar that will take place on January 28 at 14.30. The seminar will be held online via the Zoom platform. ________________________________________________________ Speaker: Christoph Thaele (University of Bochum, Germany)  Title: Poisson hyperplanes in hyperbolic space  JANUARY 28 (Friday) - 14:30 Zoom link https://unipd.zoom.us/j/88182977183 (meeting ID 881 8297 7183), available also on the webpage https://www.math.unipd.it/~bianchi/seminari/ Abstract: In the focus of this talk are random tessellations in hyperbolic space induced by Poisson point processes on the space of hyperbolic hyperplanes (totally geodesic subspaces of co-dimension 1). In the first part of the talk we consider the so-called k-skeleton of such tessellations and prove that, when observed in a sequence of increasing observation windows, the k-volume of the k-skeleton satisfies a central limit theorem only for dimensions 2 and 3 and that asymptotic normality fails in all higher dimensions. In the second part of the talk we determine the non-Gaussian limiting distribution for the special case k=d-1 and indicate possible generalizations. On behalf of the organizers, Marco Formentin

Each vertex represents an individual which may be susceptible, infected or removed. At the beginning only one node is infected and each node $x$ has a random spread capacity $L_x$. Once infected, the node $x$ becomes an emitter and has $L_x$ attempts to infect other nodes, which are randomly chosen. If the attempt is towards a susceptible node $y$, then $y$ becomes infected, if it is towards an infected or removed node, then $x$ loses an infection attempt. > When $x$ has used all its spread capacity, it becomes removed and no longer interacts with the rest of the population. This model was studied by Comets et al. in the case where the spread capacities are i.i.d. and the nodes which one attempt to infect are chosen uniformly. > We study the case where the population is divided into J types and each type has a possibly different susceptibility, that is, some individuals have a larger probability of being chosen as targets. Also the law of the spread capacity may depend on the type. We obtain a law of large numbers and a central limit theorem for the duration of the process and the proportion of infected nodes. We prove that when the spread capacity is homogeneous, then a population with inhomogeneous susceptibility is overall less affected by the epidemics than a population with homogeneous susceptibility. > > This is joint work with J.Kampf, E.Sava-Huss and F.Zucca. > > > Webex meeting, meeting link: > > {https://tugraz.webex.com/tugraz-de/j.php?MTID=mfb7a477bc53fac8b0a6db53cf1f2690e} > > Meeting number: 2734 226 6767 > > Password: Je3q3w37mJG > > The meeting opens at 10:40, the 50min talk starts at 11:00 > > Organisator/in: W.

Seminario R. Scimone - Politecnico di Milano
by Laura Maria Sangalli 11 Jan '22

11 Jan '22

Si avvisa che in data 14-01-2022, alle ore 15:00 precise, si svolgerà online il seguente seminario: Relatore: Riccardo Scimone, Politecnico di Milano Titolo: A look at the spatio-temporal mortality patterns in italy during the covid-19 pandemic through the lens of mortality densities Sommario: With the tools and perspective of Object Oriented Spatial Statistics, we analyze official daily data on mortality from all causes in the provinces and municipalities of Italy for the year 2020, the first of the COVID-19 pandemic. By comparison with mortality data from 2011 to 2019, we assess the local impact of the pandemic as perturbation factor of the natural spatio-temporal death process. For each Italian province and year, mortality data are represented by the densities of time of death during the calendar year. In this talk, the use of a density-on-density functional linear model, formulated to decouple temporal and spatial variability, will be firstly illustrated, followed by a spatial analysis focused on identifying the spatial correlation structure of the death process before and during the pandemic. An anomaly detection framework at the very granular scale of Italian municipalities will also be described. Il link per seguire il seminario sarà reso disponibile su https://mox.polimi.it/mox-seminars/?id_evento=2117 Tutti gli interessati sono cordialmente invitati a partecipare, Laura Sangalli —— Laura Maria Sangalli MOX - Dipartimento di Matematica Politecnico di Milano Piazza Leonardo da Vinci 32 20133 Milano - Italy tel: +39 02 2399 4554 fax: +39 02 2399 4568 email: laura.sangalli(a)polimi.it<mailto:laura.sangalli@polimi.it> url: http://mox.polimi.it/~sangalli

We study the vectors $\mathbf{q}(A)=(q_x(A))_{x \in X}$ recording the conditional probabilities of extinction in subsets of types $A \subseteq X$, given that the type of the initial individual is $x$. We first investigate the location of the vectors $\mathbf{q}(A)$ in the set of fixed points. Next, we present equivalent conditions for $\mathbf{q}_x(A) < \mathbf{q}_x(B)$ for any initial type $x$ and $A,B \subseteq X$. Finally, we develop a general framework to characterise all distinct extinction probability vectors, and thereby to determine whether there are finitely many, countably many, or uncountably many distinct vectors. We illustrate our results with examples. > > This is based on joint work with D.Bertacchi, P.Braunsteins and S.Hautphenne. > > > Webex meeting, meeting link: > > {https://tugraz.webex.com/tugraz-de/j.php?MTID=m32158f79ff92d881d5eb9b4f2502cfef} > > Meeting number: 2730 713 4197 > > Password: kFvAawdJ332 > > The meeting opens at 10:40, the 50min talk starts at 11:00 > > > > Organisator/in: W.
