Seminario di Economia e Probabilita' a RM1
by Fabio Spizzichino 01 Nov '15

01 Nov '15

La Dr.ssa Eleonora Perversi (Dipartimento di Matematica, Universita' di Pavia) terrà, presso il Dipartimento di Matematica dell'Universita' La Sapienza, un seminario su *Inequality and risk aversion in economies open to altruistic attitudes* Mercoledi' 4 Novembre, ore 14.00, Aula Picone Dipartimento di Matematica, Piazzale A. Moro, Roma Tutte le persone interessate sono invitate ad intervenire Fabio Spizzichino Abstract: In recent years there has been a great interest in the phenomenon of economic inequality, especially in relation to its connection with other important aspects of an advanced economy, for example attitude towards risk, growth, financial developments, and so on. In this talk, based on a joint work with Eugenio Regazzini, I will introduce a model for the surplus/deficit distribution, which points out a relationship between agents' risk aversion and inequality. More precisely, on the one hand, the long-time surplus/deficit distribution turns out to be a weak Pareto law whose exponent is given by an affine transformation of the agents relative risk aversion index, supposed to be the same for every agent. On the other hand, it is proved that concentration in a weak Pareto law can be measured through a function of its exponent. This way, a link is established between inequality and risk aversion. Finally, some feasible actions of economic policies suitable for the control of inequality are derived.

In particular, we will give some sufficient and necessary conditions with a geometric and combinatorial flavour for a given set to be the support of an extremal martingale measure with pre-specified discrete marginals. Some open problems will be discussed as well. This is based on joint work with Claude Martini.

Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, Il Prof. ENRICO SCALAS (Department of Mathematics, University of Sussex, UK) terrà un seminario dal titolo EXACTLY-SOLVABLE NON-MARKOVIAN DYNAMIC NETWORK Abstract: Non-Markovian processes are widespread in natural and human-made systems, yet explicit modelling and analysis of such systems is underdeveloped. In this letter we consider a dynamic network with random link activation and deletion (RLAD) with non-exponential inter-event times. We study a semi-Markov random process when the inter-event times are heavy tailed Mittag-Leffler distributed, thus considerably slowing down the corresponding Markovian dynamics and study the system far from equilibrium. We derive an analytically and computationally tractable system of forward equations utilizing the Caputo derivative for the probability of having a given number of active links in the network. http://journals.aps.org/pre/abstract/10.1103/PhysRevE.92.042801 Tutti gli interessati sono invitati a partecipare. -- Federico Polito Department of Mathematics University of Torino Via Carlo Alberto, 10 10123, Torino, Italy Email: federico.polito(a)unito.it Tel: +39 011 6702937 Web: www.federicopolito.it

Politecnico di Milano - Seminari Jim Ramsay e Michelle Carey
by Laura M. Sangalli 28 Oct '15

28 Oct '15

Si avvisa che in data 6-11-2015, alle ore 10:30 precise, presso l'Aula Seminari "F. Saleri" VI piano - Dipartimento di Matematica, Politecnico di Milano, nell'ambito delle iniziative MOX, si svolgeranno i seguente seminari: ore 10:30 Jim Ramsay, McGill University, Exploring Functional Data with Dynamic Models ore 11:30 Michelle Carey, McGill University, Data2PDE: an iterative scheme for obtaining data driven estimates of the parameters of PDEs defined over complex domains Seguono gli abstracts dei due seminari. Jim Ramsay Exploring Functional Data with Dynamic Models Discrete observations of curves are often smoothed by attaching a penalty to the error sum of squares, and the most popular penalty is the integrated squared second derivative of the function that fits the data. But it has been known since the earliest days of smoothing splines that, if the linear differential operator D^2 is replaced by a more general differential operator L that annihilates most of the variation in the observed curves, then the resulting smooth has less bias and greatly reduced mean squared error. This talk will show how we can use the data to estimate such an operator. The differential equation estimated in this way is already an interesting model for the data that represents the dynamics of the processes being estimated. But, in addition to the advantages in bias and MSE, it emerges that exciting new ways of representing the data emerge that use an orthogonal basis system defined by the estimated operator. M. Carey Data2PDE: an iterative scheme for obtaining data driven estimates of the parameters of PDEs defined over complex domains Spatial data are abundant in many scientific fields, some examples include; satellite images of the earth, temperature readings from multiple weather stations and the spread of an infectious disease over a particular region. In many instances the spatial data are accompanied by mathematical models expressed in terms of partial differential equations (PDEs). These PDEs determine the theoretical aspects of the behaviour of the physical, chemical or biological phenomena considered. The parameters of the PDEs are typically unknown and must be inferred from expert knowledge of the phenomena considered. In this talk I will discuss extending the profiling with parameter cascading procedure outlined in Ramsay et al (2007) to incorporate PDE parameter estimation. Furthermore, following from Sangalli et al. (2013) the estimation procedure is extended to include nite element methods (FEMs). This allows the proposed method to account for attributes of the geometry of the physical problem such as irregular shaped domains, external and internal boundary features and strong concavities. Thus this talk introduces a methodology for data driven estimates of the parameters of PDEs dened over complex domains. Tutti gli interessati sono invitati a partecipare.

PIETRO CAPUTO - GIOVEDI 29 - TOR VERGATA - CICLO SEMINARI PASCAL
by Valentina Cammarota 27 Oct '15

27 Oct '15

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Giovedi` 29 ottobre ore 15:00 Aula Dal Passo Dipartimento di Matematica Università di Roma Tor Vergata Prof. Pietro Caputo Dipartimento di Matematica e Fisica, Università Roma Tre Titolo: Dynamical phase transition in random lattice triangulations Abstract: We consider lattice triangulations, i.e., triangulations of the integer points in Euclidean plane. Our focus is on random triangulations in which a triangulation \sigma has weight \lambda^{|\sigma|}, where \lambda is a positive real parameter and |\sigma| is the total length of the edges in \sigma. Empirically, this model exhibits a phase transition at \lambda=1 (corresponding to the uniform distribution): for \lambda<1 distant edges behave essentially independently, while for \lambda>1 very large regions of aligned edges appear. We substantiate this picture as follows. For \lambda<1 sufficiently small, we show that correlations between edges decay exponentially with distance (suitably defined), and also that the Glauber dynamics, namely the local Markov chain based on flipping edges, is rapidly mixing (in time polynomial in the number of edges in the triangulation). By contrast, for \lambda>1 we show that the mixing time is exponential. For thin rectangular regions we obtain sharp mixing time bounds for all values of \lambda<1. This is joint work with F. Martinelli, A. Sinclair and A. Stauffer Tutti gli interessati sono invitati a partecipare. .
