Apologies for cross posting --------------------------------- SEMINARIO DI MATEMATICA APPLICATA Giovedi 23 Ottobre 2014, ore 11.30 Aula Rappresentanza, Dipartimento di Matematica (Via Saldini 50, Milano) Heterogeneities and the spatial spread of infectious diseases Dr. Vittoria Colizza INSERM & Universite Pierre et Marie Curie (Paris, France) ISI Foundation (Turin, Italy) ABSTRACT The spatial spread of infectious diseases depends on the interplay between local interactions among hosts (and possibly with vectors), along which transmission can occur, and dissemination opportunities presented by the movements of hosts (and vectors) among different communities or locations in space. Many degrees of heterogeneity may characterize this process, induced by large fluctuations in hosts' features (e.g. mixing behavior, frequency and duration of movements, topology and magnitude of movement fluxes) or by variations in pathogen's specific features (e.g. multiple circulation of different viruses, multiple types of transmission). To address these aspects, I'll present a general theoretical modeling framework taking into account the various heterogeneities at play and explore how these may affect the pandemic potential of an emerging infectious disease. Results are discussed in the realm of specific case studies.

Seminario KNAPIK
by Matteo Ruggiero 17 Oct '14

17 Oct '14

**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Venerdi' 24 Ottobre 2014 alle ore 12:00, presso la sala rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Bartek KNAPIK (Vrije Universiteit Amsterdam) CONVERGENCE RATES OF POSTERIOR DISTRIBUTIONS IN NONPARAMETRIC INVERSE PROBLEMS Abstract: Since the seminal works of Ghosal, Ghosh and van der Vaart (2000) and Shen and Wasserman (2001), posterior contraction has attracted much attention, resulting in the rich literature on this subject. However, these results are not suitable to deal with trully ill-posed inverse problems, where one is interested in the parameter of interest f, given noisy observations of its transformed version Kf. General theorems yield contraction results in some metric measuring the distance between Kf and Kf_0, whereas the interest lies in the distance betweend f and f_0, and these two metrics are not equivalent. In this talk we review (a part of) the existing literature on Bayesian approach to nonparametric inverse problems, and present a general contraction theorem. We show that in mildly ill-posed problems with conjugate priors, both empirical and hierarchical Bayes approaches lead to (nearly) optimal recovery of an infinite-dimensional parameter of interest. Moreover, using our general result, we obtain minimax adaptive concentration rates in two examples in the fixed-design regression setting. Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto.

Seminario Kirone Mallick a Roma

The Asymmetric Simple Exclusion Process, a Review by Kirone Mallick (CEA, Saclay, Francia) Monday, 20 October 2014 from 16:00 to 18:00 (Europe/Rome) at Dip. di Fisica - Edificio G. Marconi ( Aula Conversi ) Abstract The asymmetric simple exclusion process plays the role of a paradigm to study various aspects of non-equilibrium statistical physics. It is a minimal model of interacting particles with transport, that displays interesting collective behaviour and breaks time-reversal symmetry. This system appears as a building block in more realistic descriptions of low-dimensional transport with constraints. During the last twenty years, a large number of exact results have been derived for the exclusion process. The aim of this talk is to review the main techniques used to study this system and some of the important results that have been obtained.

MOSTRA e CONFERENZA sul matematico René Gateaux
by Nappo, Giovanna 16 Oct '14

16 Oct '14

Vi segnalo la Mostra (21.24 ottobre) e la conferenza (21 ottobre) su René Gateaux presso il Dipartimento di Matematica Università di Roma "La Sapienza" MOSTRA René Gateaux (1889-1914) Itinerario di una gioventù perduta: Dipartimento di Matematica "Guido Castelnuovo" Università di Roma "La Sapienza" 21 -24 ottobre 2014 René Gateaux era un giovane matematico francese. Circa un milione e mezzo di francesi sono morti durante la Prima Guerra Mondiale, e René Gateaux è stato uno di loro. Qualche tempo prima della sua prematura scomparsa, avvenuta nella notte tra il 2 e il 3 ottobre 1914, ebbe diversi contatti scientifici con la comunità matematica romana e in particolare con Vito Volterra. In occasione del centenario dalla morte di René Gateaux, nei locali del Dipartimento di Matematica Guido Castelnuovo (piano terra), si terrà una mostra sui suoi contributi scientifici e sulla sua breve vita: il caso di René Gateaux apporta qualche interessante contributo alla conoscenza del suo periodo storico. La mostra si può visitare durante l'orario di apertura del Dipartimento di Matematica: dalle 8 alle 20. L'ingresso è gratuito Consulenti scientifici: Laurent Mazliak (Université Pierre et Marie Curie, Paris) e Rossana Tazzioli (Université de Lille 1) Concezione grafica: Raphaël Petit Organizzazione locale: Giovanna Nappo e Fabio Spizzichino (Dipartimento di Matematica) CONFERENZA Martedì 21 ottobre, ore 15:30, in Aula Picone del Dipartimento di Matematica "Guido Castelnuovo", il Professor Laurent Mazliak terrà una conferenza introduttiva. René Gateaux (1889-1914) abstract: Nell'ottobre 1914, il giovane matematico René Gateaux fu ucciso nei primi combattimenti della prima guerra mondiale. Aveva 25 anni. La sua fortuna postuma fu di essere stato, durante la sua breve vita, in relazione con importanti matematici, in particolare con Vito Volterra, e di avere lasciato prima di andare in guerra delle carte che diventarono, nelle mani esperte di Paul Lévy, la fonte di sviluppi capitali per la matematica del '900. Nella conferenza, considerata come un'introduzione e un complemento alla mostra omonima presso il Dipartimento di Matematica "Guido Castelnuovo", verranno presentati diversi aspetti di questo sorprendente destino. La conferenza sarà preceduta da una breve introduzione alla derivata di Gateaux, tenuta dal Prof. Antonio Siconolfi (Università di Roma "La Sapienza").

Fractional Calculus, Probability and Non-Local Operators: Second (and final) call for papers.
by Enrico Scalas 15 Oct '14

15 Oct '14

Second Call for papers Second Workshop on Fractional Calculus, Probability and Non-Local Operators: Applications and Recent Developments BCAM, Bilbao, Basque Country - Spain 10-14 November 2014 Research on non-local operators and related stochastic processes has witnessed a rapid expansion over the past years. These problems pose new challenges to both pure and applied mathematicians, at the interface of at least three wide fields: functional analysis, stochastic processes and partial differential equations, while providing a new paradigm in scientific modelling. Applications range from relativistic models of quantum physics and quantum field theory, to sub-diffusion experimentally observed in molecular physics, from anomalous transport in cells to leptokurtic price distributions in financial markets, or to long-range dynamics ranging from the nano-scale to the geophysical scale. This interaction between mathematics and applications is giving rise to new concepts and methods, and it will produce new challenging mathematical problems for many years to come. Programme Monday 10th - Wednesday 12th Mon 11:30-13:30 / 15:00-19:00 Tue 9:00-12:00 / 15:00-16:00 / 17:00-19:00 Wed 9:00-12:00 / 15:00–18:00 PhD/PostDoc level course on "Fractional Kinetics: Analytic and Probabilistic Approaches" Vassili Kolokoltsov (University of Warwick, UK) Jozsef Lorinczi (Loughborough University, UK) Enrico Scalas (University of Sussex, UK) Tue 16:00-17:00 BCAM Scientific Seminar J.
