Seminario di Probabilità - Padova - Rettifica orario
by Paolo Dai Pra 25 Sep '17

25 Sep '17

A causa di un mio errore il seguente seminario era stato annunciato ad un orario errato, quello corretto è 10:30. Ecco l’annuncio corretto: Ho il piacere di invitarvi al seguente seminario, che si terrà Martedì 26 Settembre, alle 10:30, in aula 2AB45 della Torre Archimede presso il Dipartimento di Matematica dell'Università degli Studi di Padova. SPEAKER: Paolo Pigato AFFILIATION: WIAS, Berlino TITLE: The Oscillating Brownian motion: estimation and application to volatility modeling ABSTRACT: We consider a continuous time stochastic process which exhibits a regime-switch in the dynamics accordingly to a certain threshold. This process is solution to a stochastic differential equation with piecewise constant coefficients. We introduce and analyze estimators for the diffusion coefficient, the drift coefficient, and the threshold level. We use this process as a local volatility model for financial indices, that we test on time series of daily prices of several assets, finding evidence of leverage effect (negative correlation between prices and volatilies) and of mean-reversion effects in the dynamics of the prices.

Annuncio seminario di probabilita', Pisa, 26.09.2017

Seminar announcement of the probability seminar at the University of Pisa DATE AND TIME: Tuesday, september 26, 09:15h - 11:00h LOCATION: Aula Seminari, Dipartimento di Matematica, Universita' di Pisa SPEAKER: Nicolas Perkowski TITLE: A weak universality result for the parabolic Anderson model ABSTRACT: We consider a class of nonlinear population models on a two-dimensional lattice which are influenced by a small random potential, and we show that on large temporal and spatial scales the population density is well described by the continuous parabolic Anderson model, a linear but singular stochastic PDE. The proof is based on a discrete formulation of paracontrolled distributions on unbounded lattices which is of independent interest because it can be applied to prove the convergence of a wide range of lattice models. This is joint work with Jörg Martin. Everyone is invited to participate. For more information, please contact carina.geldhauser(a)dm.unipi.it

Avviso seminario
by Stefano Bonaccorsi 18 Sep '17

18 Sep '17

Scusandomi per il breve preavviso, inoltro il seguente avviso di seminario. The Enskog Process *September 21, 2017* *Venue:* Seminar Room “-1” – Department of Mathematics - Via Sommarive 14 - Povo -Trento at *11:00 a.m.* - *Barbara Rüdiger-Mastandrea (*Bergische Universität Wuppertal) *Abstract: * (Joint article with S. Albeverio, P. Sundar, appeared on Journal Stat. Physics, January 2017 (No1)) The existence of a weak solution to a McKean-Vlasov type stochastic differential system corresponding to the Enskog equation of the kinetic theory of gases is established under suitable hypotheses. The distribution of any solution to the system at each fixed time is shown to be unique. The existence of a probability density for the time-marginals of the velocity is verified in the case where the initial condition is Gaussian, and is shown to be the density of an invariant measure. *Contact person: *Stefano Bonaccorsi *Staff Dipartimento di Matematica* *Università degli Studi Trento*Via Sommarive, 14 38123 Povo (TN) Tel +39 0461/281625-1701-3786

Call for papers in a special issue on "Financial Mathematics"- Mathematics
by Antonella Basso 14 Sep '17

14 Sep '17

The journal Mathematics (ISSN 2227-7390) is currently running a Special Issue entitled "Financial Mathematics". Prof. Dr. Antonella Basso, of the Department of Economics, Ca’ Foscari University of Venice, (Venice, Italy), is serving as Guest Editor for this issue. The purpose of this Special Issue is to establish a collection of articles that reflect the latest mathematical methods and models in the field of financial mathematics, a bridge between mathematical theory and its applications to finance. [...] For further reading, please follow the link to the Special Issue Website at: http://www.mdpi.com/si/mathematics/Financial_Mathematics_2017 The submission deadline is 31 March 2018. You may send your manuscript now or up until the deadline. Submitted papers should not be under consideration for publication elsewhere. We also encourage authors to send a short abstract or tentative title to the Editorial Office in advance (mathematics(a)mdpi.com). Mathematics is fully open access. Open access (unlimited and free access by readers) increases publicity and promotes more frequent citations, as indicated by several studies. Open access is supported by the authors and their institutes. An Article Processing Charge (APC) of CHF 350 currently applies to all accepted papers.
