Padua Probability Seminar: Anna Vidotto
by Markus 18 May '22

18 May '22

Dear All: Next Wednesday,*Anna Vidotto* (Università degli Studi di Napoli Federico II) will give a seminar talk on the Excursion Area of Time Dependent Spherical Random Fields, which will be held in person and online via Zoom. Details: * Date and time: Wednesday, May 25, 2022 at 14.30 pm * Place: room 2AB40 at the Department of Mathematics, University of Padua (Torre Archimede, via Trieste, 63, 35121 Padova) * Zoom link: please visit the webpage https://www.math.unipd.it/~bianchi/seminari/ * Title: On the Excursion Area of Time Dependent Spherical Random Fields * Abstract: In this talk, we consider isotropic and stationary real Gaussian time dependent random fields defined on the two dimensional unit sphere S^2 and we investigate the asymptotic behavior, as T tends to infinity , of the excursion area in S^2 × [0, T] at any threshold, covering both cases when the field exhibits short and long memory, that is, integrable and non-integrable temporal covariance. It turns out that the limiting distribution is not universal, depending both on the memory parameters and the threshold. The talk is based on a joint work with D. Marinucci and M. Rossi.

(PMS)^2 online talk: Sonia Mazzucchi
by margherita Zanella 18 May '22

18 May '22

Dear colleagues, we are happy to announce the following online talk: Speaker: Sonia Mazzucchi (Università di Trento) Title: Chernoff approximations for Feller semigroups in Riemannian manifolds. Abstract: In this talk I shall present the construction of Chernoff approximations for Feller semigroups in Riemannian manifolds of bounded geometry. This result provides approximations for solutions to initial-value problems for parabolic equations with variable coefficients on the manifold. It also yields the weak convergence of particular sequences of random walks on the manifolds to the diffusion processes associated with the elliptic generator. For parallelizable manifolds this result is applied in particular to the representation of the Brownian motion on the manifold as limit of the corresponding random walks. Date and time: Monday May 23, 17:30-18:30 (Rome time zone).

OGGI: seminario su "Comparative gene finding on highly diverse chromosome alleles", Marina Axelson-Fisk 17 May
by Umberto Picchini 17 May '22

17 May '22

/[questo e' il nuovo annuncio di un seminario per //*oggi*//17 Maggio che era stato precedentemente cancellato]/ You are welcome to the next Statistics seminar at Dept of Mathematical Sciences at Chalmers and Göteborg University. On Tuesday May 17, Marina Axelson-Fisk <http://www.math.chalmers.se/~marinaa/> will talk of: ///"Comparative gene finding on highly diverse chromosome alleles" / * * marina axelson-fisk *About the speaker: *Marina Axelson-Fisk <http://www.math.chalmers.se/~marinaa/> is a Professor in Mathematical Statistics at Chalmers and University of Gothenburg. She works mainly within the field of Bioinformatics, with particular focus on stochastic models and algorithms for comparative genomics and cross-species gene finding. She is an associate member of the Linnaeus Centre for Marine Evolutionary Biology (CeMEB), where she is involved in the bioinformatics analysis of a number of newly sequenced Swedish coastal organisms. ** *Abstract:* With the new sequencing technologies, the number of novel genome sequences has exploded. At the same time the genome projects are hampered by the lack of homologies to the novel genome, making it difficult both to properly train genome analysis tools and to assess the results. Moreover, the faster and cheaper sequencing methods come with the cost of data quality, and sequencing and annotation errors that make it into the genome databases are propagated to new genomes, making annotation an even bigger challenge. Methods that can improve the data quality is desperately needed. Here we propose a novel use of comparative gene finding to improve the annotation in organisms with high nucleotide diversity. Comparative gene finding methods utilizes the contrast in sequence similarity between functional and non-functional regions of evolutionary related species. We show how this can be applied to chromosome pair sequences in diploid sequence data. We demonstrate the approach on the highly diverse sea orchid Balanus improvisus using SLAM, a cross-species gene finder that simultaneously annotates and aligns two homologous sequences using Generalized Pair Hidden Markov Models.* * *Feel free to spread this announcement in your network.* * * *Where*: room MVL14 or https://chalmers.zoom.us/j/62177902216 Password: 786749 ** **** *When*: Tuesday May 17 at 14.30-15.30*(Swedish time, UTC+2)*. ** -- _________________________________________________________ Umberto Picchini, Associate Professor, PhD, Docent https://umbertopicchini.github.io/ , twitter: @uPicchini

Seminars in Pisa: L. Andreis and G. Carigi
by Francesco Grotto 16 May '22

16 May '22

Dear Colleagues, we would like to invite you to the following seminars by Luisa Andreis (Università di Firenze) and Giulia Carigi (University of Reading) to be held Wednesday, May 18th, at Dipartimento di Matematica in Pisa and online via Google Meets. The organizers, A. Agazzi and F. Grotto -------------------------------------------- Location: Sala Seminari, Dipartimento di Matematica, Pisa Google Meet Link: https://meet.google.com/gji-phwo-vbg Time: May 18th, 2022, 14:00-15:00 CET Speaker: Luisa Andreis (UniFi) Title:Large deviations for coagulation processes: an approach via graphs Abstract: Interacting particle systems where particles interact via coagulation are of great interest for their various behaviours. In particular, interesting phenomena can occur, depending on the structure of the kernel which is giving a rate to each coagulation. Among these phenomena there is the famous phase transition that goes under the name of gelation, i.e. the appearance of one (or multiple) giant particle(s). Although fluid limits are known for the rescaled version of stochastic coagulation processes (convergence to the Smoluchowski coagulation equation and its modification), very few is known about large deviations and rare events in this framework. In this talk we will explore some connections of these processes with random graphs and how to use this connection to attack the problem of studying large deviations. This also allows a comparison with the phase transition in graphs, where a giant component appears. Some remarks about the possible generalization to coagulation kernels that depend on spatial position will be given. This is based on ongoing joint works with Wolfgang K ̈onig (WIAS and TU Berlin), Tejas Iyer (WIAS), Heide Langhammer (WIAS), Elena Magnanini (WIAS) and Robert Patterson (WIAS). Time: May 18th, 2022, 15:00-16:00 CET Speaker: Giulia Carigi (University of Reading) Title: Ergodic properties for a stochastic two-layer model of geophysical fluid dynamics Abstract: A two-layer quasi-geostrophic model for geophysical flows is studied, with the upper layer being perturbed by additive noise. This model is popular in the geosciences, for instance to study the effects of a stochastic wind forcing on the ocean. A rigorous mathematical analysis however meets with the challenge that the noise configuration is spatially degenerate as the stochastic forcing acts only on the top layer. Exponential convergence of solutions laws is established, implying a spectral gap of the associated Markov semigroup on a space of Hölder continuous functions. Moreover, response theory with respect to changes in the average wind forcing is established. Specifically, it is shown that the averages of a class of observables against the invariant measure are differentiable (linear response) and locally Hölder continuous (fractional response) as functions of a deterministic additive forcing. In doing so, a framework suitable to establish (linear and fractional) response for a class of nonlinear stochastic partial differential equations is provided.
