15 Jul '14

IMATI-Milano organizes the 1st Workshop on Computer-aided and bio-chemical strategies for the design of stochastic experiments, on July, 31st. This Workshop will bring together scientists and engineers from industry and academia to identify current limitations, needs and trends in tackling experimental stochastic system in natural sciences. The workshop will consist of a number of keynote lectures, followed by breakout sessions focused on developing solutions to the challenges of method development, specifically advancing and accelerating methods for broad applications. The program with all information can be downloaded here http://www.mi.imati.cnr.it/iami/Workshop_Borrotti_2014_07_31.pdf Anyone interested to attend the Workshop is kindly invited to send an e-mail to Matteo Borrotti: matteo AT mi.imati.cnr.it We apologize for cross posting. -- Dott.

Workshop announcement Random Structures and Models in Medicine, Biotechnology, Materials Science and Environment https://sites.google.com/site/randomstructures/home September 12, 2014 Department of Mathematics Universita' degli Studi di Milano via Saldini 50, Milano, Italy This workshop is an activity of the ECMI Special Interest Group "Shape and Size in Medicine, Biotechnology and Materials Science" (see http://www.mat.unimi.it/users/shape/) and is aimed to give an overview to methods developed in Mathematical Morphology, Spatial Statistics, Stochastic Geometry, Numerical Analysis to model and to simulate random sets and functions with a spatial or geometrical structure. These models are useful in many applications where heterogeneous media, possibly evolving in time, appear, for instance materials, networks of vessels, evolution of pollutants, etc. Both theoretical and applied results will be discussed. All the talks are invited, but participation is free and encouraged. Registration of participants is required for organizing reasons by September 7, 2014.

mini-workshop "Young Researchers" a Milano-Bicocca
by Fabio Bellini 11 Jul '14

11 Jul '14

Il giorno giovedì 17 luglio alle ore 14.30 presso la Sala del Consiglio della Scuola di Economia e Statistica, al IV piano dell'edificio U7 in via Bicocca degli Arcimboldi 8, si terrà il mini-workshop "Young Researchers" con il seguente programma: 14.30 - 15.00 Annamaria Gambaro, Dottorato in Statistica e Matematica per la Finanza, Curriculum Matematica per la Finanza, Università di Milano-Bicocca Approximated pricing of swaptions in general interest rate models We propose a new lower bound on the prices of European-style swaptions for a wide class of interest rate models. This method is applicable whenever the joint characteristic function of the state variables is known in closed form or could be easily obtained with numerical PDE solution method. Our algorithm involves the computation of one dimensional Fourier transform indipendently from the swap length. Moreover the bound could be used as a control variable to reduce confidence interval of the Monte Carlo technique. We test our new lower bound on different affine models and on 2-factor quadratic gaussian model and the method is found to be fast and accurate (joint work with Ruggero Caldana and Gianluca Fusai). 15.00 - 15.30 Jacopo Corbetta, Dottorato in Matematica e Applicazioni, Università di Milano-Bicocca Smile asymptotics in a multiscaling stochastic volatility model We consider a stochastic volatility model which captures some relevant stylized facts of financial series, including the so-called multiscaling of moments. We obtain sharp large deviations estimates for the price, based on a large deviations principle for suitable functionals of a point process, which is of independent interest. This yields explicit asymptotic formulas for the price of European options, and for the related implied volatility, both in the small maturity and large strike regimes. In particular, we show that implied volatility for out-of-the-money options explodes as the maturity vanishes, with an explicit limiting shape (joint work with Francesco Caravenna). 15.30 - 16.00 Alberto Santangelo, Dottorato in Statistica e Matematica per la Finanza, Curriculum Matematica per la Finanza, Università di Milano-Bicocca Measuring Portfolio Diversification Based on Optimized Uncorrelated Factors We measure diversification in terms of the "Effective Number of Minimum-Torsion Bets", namely a set of uncorrelated factors, optimized to closely track the factors used to allocate the portfolio. In this way we introduce a novel notion of "absolute risk contributions", which generalizes the "marginal contributions to risk" in traditional risk parity. We discuss the advantages of the Minimum-Torsion Bets over the traditional approach to diversification based on marginal contributions to risk. We present a case study in the S&P 500. Fully documented code is available for download (joint work with Romain Deguest and Attilio Meucci). Tutti gli interessati sono invitati a partecipare.

Seminario Alcuni aspetti dell'impostazione "Target-Based" alle funzioni di utilità nel caso di più "beni"
by Marco Isopi 08 Jul '14

08 Jul '14

Nell'ambito dei seminari previsti a completamento dell'attività svolta nell'ambito del Dottorato di Ricerca in Matematica XXVI Ciclo (curriculum Matematica Applicata) Fabio Fantozzi terrà un seminario dal titolo Alcuni aspetti dell'impostazione "Target-Based" alle funzioni di utilità nel caso di più "beni" Il seminario si terrà in Aula di Consiglio, Giovedi' 10 Luglio ore 16 Sunto: Verrà inizialmente richiamato il significato dell'impostazione Target-Based alla teoria dell'utilità nelle scelte economiche in condizioni di incertezza. Tale impostazione, dapprima introdotta nel caso di un singolo "bene" è stata, nell'ultimo decennio, estesa e sviluppata per il caso di n beni. Nel seminario verranno illustrate in particolare le caratteristiche fondamentali di tale caso e ne verrà introdotta una descrizione formale. In tale ambito saranno evidenziate le connessioni con le misure di insieme monotone, non necessariamente additive (capacità), su spazi finiti e relative estensioni. In particolare analizzeremo il significato di tali estensioni in termini di copule n-dimensionali atte a descrivere la dipendenza stocastica fra le componenti di un vettore aleatorio. Quest' ultimo interviene, con il significato di "target", nella formulazione delle funzioni di utilità stesse. In relazione ai problemi di scelte economiche analizzati, verranno anche brevemente illustrati degli aspetti relativi alla nozione di "stochastic precedence". *******************************************
