The geometric invariants are the fixed length of a random chain and the constant radius of a sphere, which is the surface for random walks (for example, in the case of a turning diffusion). The integral invariants are represented as integrals of kernel functions of integral invariants on the whole space. These kernel functions are solutions of SDEs, which were obtained and discussed. Furthermore, kernel functions will be used for deriving the first global stochastic integral, for constructing the program control (with probability one) for stochastic dynamical systems on deterministic manifold based on Brownian motion with Poisson jumps, and for obtaining the Kolmogorov equations.

secondo annuncio: mini corso del Prof. Gentil a Pavia
by Carbone Raffaella 09 Jan '14

09 Jan '14

Cari colleghi, vi ricordiamo che il prof. Ivan Gentil (Université Lyon 1) terrà, presso il Dipartimento di Matematica dell'Università di Pavia, un mini-corso dal titolo The Bakry-Emery condition applied to the functional inequality and contraction in Wasserstein distance Abstract : During the lessons we would like to introduce the Bakry-Emery condition in the Euclidean space R^n and also in a Riemannian manifold. First we study the two classical examples: the Euclidean Heat semigroup and the Ornstein-Uhlenbeck semigroup. Then we define the general setting: a Markov semigroup associated to the Gamma and the Gamma-2 operators. Under the Bakry-Emery condition we obtain coercive inequalities which implies for instance functional inequality such as Poincaré or logarithmic-Sobolev inequalities. The last part of the course is devoted to the contraction in wasserstein distance under the Bakry-Emery condition. Orario (provvisorio): ore 11-13 nei giorni 14, 15, 17, 20, 22, 24 gennaio 2014.

de Finetti Risk seminar - gennaio 2014
by Emanuela Rosazza Gianin 08 Jan '14

08 Jan '14

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture PREFERENCE TO DIVERSIFICATION: DIFFERENT BUT INTRICATE DIMENSIONS OF UNCERTAINTY AVERSION Samuel Drapeau ABSTRACT We study the preferences of agents for diversification and better outcomes when they are facing both, in Frank Knight's formulation, measurable as well as unmeasurable uncertainty. Following Anscombe and Aumann, such a situation can be modeled by preferences expressed on stochastic kernels, that is scenario dependent lotteries. By means of automatic continuity methods based on Banach-Dieudonné's Theorem on Fréchet spaces, we provide a robust representation. This gives us some insight into the nature of uncertainty aversion these preferences are expressing. We further investigate under which conditions these two intricate dimensions of uncertainty can be disentangle into a distributional uncertainty, in the direction of von Neumann and Morgenstern's theory, and a probability model uncertainty, in the spirit of risk measures. These results allow in particular to address both Allais as well as Elsberg's paradox. LOCATION: The seminar will be held on Wednesday, 15 January, at 18.00 at Aula di Rappresentanza, Department of Mathematics, Milano University, Via Saldini 50, Milano. A refreshment will be offered at 17.30. Scientific Committee: Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ. Bocconi) Prof. Massimo Marinacci (Univ.

Seminario Prof.ssa Youngna Choi @ SNS Pisa
by Giacomo BORMETTI 06 Jan '14

06 Jan '14

Buongiorno a tutti, vi segnalo il seminario della Prof.ssa Youngna Choi della Montclair State University che si terrà a Pisa presso la Scuola Normale Superiore il prossimo 9 Gennaio alle ore 13:00 in Aula Bianchi. Seguono titolo e abstract. Titolo: Financial Instability Contagion: a Dynamical Systems Approach Abstract: We build a multi-agent dynamical system for the global economy to investigate and analyze financial crises. The agents are large aggregates of a subeconomy, and the global economy is a collection of subeconomies. We use well-known theories of dynamical systems to represent a financial crisis as propagation of a negative shock on wealth due the breakage of a financial equilibrium. We first extend the framework of the market instability indicator, an early warning signal defined for a single economy as the spectral radius of the Jacobian matrix of the wealth dynamical system. Then, we formulate a quantitative definition of instability contagion in terms thereof. Finally, we analyze the mechanism of instability contagion for both single and multiple economies. Our contribution is to provide a methodology to quantify and monitor the level of instability in sectors and stages of a structured global economic model and how it may propagate between its components. Tutti gli interessati sono cordialmente invitati.

The emphasis is on the analysis of the model and the tools for asymptotic inference. The results are illustrated by a few examples. A number of extensions of the theory are pointed out.// */Challenges for Macroeconomic Theory/* Standard macroeconomic models were not able to foresee our recent crisis nor have they been very useful for guiding us out of the subsequent long recession. Most of the economics profession has, therefore, acknowledged the need for a new research vision in macroeconomics and macrofinance. This talk discusses a number of challenges and argues that we need theoretical models that can capture the full dynamics of financial market behavior and its interrelatedness with the real economy as well as empirical models that can take such models to the data without compromising high scientific standards. How to combine these two goals is the subject of the talk. -- Prof.ssa Julia Mortera Dipartimento di Economia Università Roma Tre Via Silvio D'Amico 77 00145 Roma Tel: +39 06 57335732 Fax: +39 06 57335771 http://dipeco.uniroma3.it/docenti.asp?id=123# --- Questa e-mail è priva di virus e malware perché è attiva la protezione avast!
