Seminario di N. Torri a Milano-Bicocca (05.07.2016)
by Francesco Caravenna 30 Jun '16

30 Jun '16

Martedì 5 luglio 2016 alle ore 10:30, nell'aula 3014 del Dipartimento di Matematica e Applicazioni dell'Università di Milano-Bicocca (edificio U5, via Cozzi 55, Milano), Niccolò Torri (Université de Nantes) terrà un seminario dal titolo "Interacting prudent self-avoiding walk" Trovate il sommario di seguito. Tutti gli interessati sono invitati a partecipare. Francesco Caravenna %%%%%%%%%%%%%%%%%% Abstract: The collapse transition of self-interacting random walks is a challenging issue, arising in the study of an homopolymer dipped in a repulsive solvent. Different mathematical models have been built by physicists to try and improve their understanding of this phenomenon. For such models, the possible spatial configurations of the polymer are provided by self-avoiding walk trajectories. However, self avoiding walks, especially in dimension 2 and 3, are complicated objects. This is the reason why, in the mathematical literature, collapse transition models were rather built by either relaxing the self-avoiding feature of the walk or by considering partially directed path. In our main result, we prove the existence of a collapse transition for a non-directed model built with prudent paths, i.e., non-directed self-avoiding paths which can not take a step towards a previously visited lattice site. The prudent self-avoiding walk has attracted the attention of the combinatorics community over recent years and an open problem is to find out the exponential growth rate of the set of prudent paths. As a by product of our results we are able to solve this problem. In the first part of the talk we discuss the main models already studied in the literature, while in the second part of the talk we present our main results. The presentation will be kept at an elementary level: only a basic probabilistic background is assumed.

seminario di A. Hocquet a Pisa
by Marco Romito 28 Jun '16

28 Jun '16

Il giorno 5 luglio 2016, alle ore 11:30, presso la sala seminari del Dipartimento di Matematica dell'Università di Pisa, si terrà il seguente seminario: A. Hocquet (TU Berlin): Finite-time singularities of the stochastic harmonic map flow on surfaces. Abstract: A ferromagnetic material possesses a magnetization, which, out of equilibrium, satisfies the Landau-Lifshitz-Gilbert equation (LLG). Thermal fluctuations are taken into account by Gaussian space-time white noise. At least in the deterministic case, there is an important parallel between this model and the so-called Harmonic Map Flow (HMF). This was originally used by geometers (in the early sixties) as a tool to build harmonic maps between two manifolds u:M->N. The case where M is two dimensional is critical, in the sense that the natural energy barely fails to give well-posedness. We do not address here the problem of the solvability of LLG driven by space-time white noise. Instead, we consider a spatially correlated version. We show that oppositely to the deterministic case, blow-up of solutions happens no matter how we choose the initial data. Tutti gli interessati sono invitati a partecipare. m.

Seminario Simone Scotti a Padova
by Giorgia Callegaro 23 Jun '16

23 Jun '16

Buongiorno a tutti, annuncio con piacere che il giorno *1° luglio 2016 alle ore 15 *Simone Scotti (Université Paris VII) terrà, presso l'aula 2BC30 del Dipartimento di Matematica dell'Università di Padova (Via Trieste 63, Padova) un seminario dal titolo: "Branching processes with applications to finance" Abstract: We introduce a class of interest rate models, called the \alpha-CIR model, which gives a natural extension of the standard CIR model by adopting the \alpha-stable Lévy process and preserving the branching property. This model allows to describe in a unified and parsimonious way several recent observations on the sovereign bond market such as the persistency of low interest rate together with the presence of large jumps at local extent. We emphasize on a general integral representation of the model by using random fields, with which we establish the link to the CBI processes and the affine models. Finally we analyze the jump behaviors and in particular the large jumps, and we provide numerical illustrations.
