Seminario di Scotti a Firenze, lunedì 23 aprile 14.30: Branching Processes with applications in Finance
by Cecilia Mancini 19 Apr '18

19 Apr '18

Il giorno lunedì 23 aprile, ore 14.30 Simone Scotti, Università Diderot di Parigi (Parigi 7), terrà il seminario dal titolo Branching Processes with applications in Finance presso l'edificio D6, via delle Pandette 9, 50127 Firenze, del polo di Novoli, in aula D6/104. Tutti gli interessati sono cordialmente invitati a partecipare Abstract: I processi di Branching con immigrazione (CBI) sono una classe di processi ben studiati in probabilità. In particolare i lavori di Dawson e Li hanno fornito una scrittura esplicita per l'EDS di un CBI generale e provato l'unicità della soluzione. Utilizzeremo questa scrittura per proporre un estensione del modello CIR includendo una parte di salto nel meccanismo di Branching, considerando in particolare il caso alpha-stabile per la sua parsimonia e la coerenza con i dati statistici. Questo modello ha mostrato di essere capace di riprodurre la persistenza dei bassi tassi d'interesse malgrado la presenza di importanti grandi salti. L'applicazione principale a cui ci interesseremo è un estensione del modello di Heston includendo salti auto-eccitati sul processo di varianza. Studiamo in particolare il comportamento della volatilità implicita dei derivati dell'azione e di quelli dei variance swap. Testiamo il modello sui dati del VIX. Basato su piu lavori con Guillaume Bernis, Ying Jiao, Chunhua Ma, Carlo Sgarra e Chao Zhou.

seminario presso l'Università di Milano-Bicocca, 4 maggio 2018
by daniela bertacchi 18 Apr '18

18 Apr '18

Il giorno 4 maggio alle ore 14:30 in aula 3014 del Dipartimento di Matematica e Applicazioni dell'Università di Milano-Bicocca, la dottoressa Sophie Hautphenne dell'Università di Melbourne e Politecnico di Losanna, terrà un seminario dal titolo: The probabilities of extinction in a branching random walk on a strip Tutti gli interessati sono invitati a partecipare. Abstract. We consider a class of multitype Galton-Watson branching processes with countably infinite type set X whose mean progeny matrices have a block lower Hessenberg form. For these processes, we derive partial and global extinction criteria. Our approach involves embedding a finite-type explosive Galton-Watson process in a varying environment in the original infinite-type process, and then establishing asymptotic relationships between the two processes. We study the probability of extinction in sets of types A ⊆ X , q(A). In particular, we develop conditions for q(A) to be different from the global and partial extinction probability vectors. We present an iterative method to compute the vectors q(A), and investigate their location in the set of fixed points of the progeny generating vector.

Avviso di Seminario del Prof. Claudio Macci
by Enrica Pirozzi 16 Apr '18

16 Apr '18

AVVISO di SEMINARIO Il giorno 19 Aprile 2018 ore 14:30 nella Aula E del terzo livello del Dipartimento Matematica e Applicazioni, Università di Napoli FEDERICO II, Complesso di Monte Sant'Angelo, Via Cintia, Napoli, il Prof. Claudio Macci del Dipartimento di Matematica, Università di Roma Tor Vergata, terrà un seminario dal titolo: "Asymptotic behavior of some hitting probabilities for sums of IID Gaussian random sets" Abstract: We consider sequences of partial sums of iid Gaussian random sets (with respect to the Minkowski sum) and we study the asymptotic behavior of some hitting probabilities (of suitable sets of $R^d$) for these partial sums. We also illustrate the use of the importance sampling for the estimation of these hitting probabilities by Monte Carlo simulations. We obtain the analog of well-known results for level crossing probabilities of random walks, and we refer to a version of the classical Cramér's Theorem in large deviations for random compact sets existing in the literature. Joint work with Barbara Pacchiarotti. Tutti gli interessati sono invitati a partecipare. -- Enrica Pirozzi Dipartimento di Matematica e Applicazioni Universita' di Napoli FEDERICO II Via Cintia, Monte S.Angelo, 80126, NAPOLI, ITALY Tel. 081 675634 https://www.docenti.unina.it/ENRICA.PIROZZI

Dear all, this is to announce the following: *Joint Seminar*: Dipartimento di Matematica – Centro Internazionale per la Ricerca Matematica (CIRM) BSDEs with time-delayed generators and associated path-dependent nonlinear Kolmogorov equations Thursday, 19th of April 2018 *Place*: Dipartimento di Matematica, via Sommarive, 14 - Povo (TN) - Aula Seminari "-1" Time: 10:30 *Speaker*: Adrian Zalinescu (Universitatea Alexandru Ioan Cuza - Iaşi, Romania) *Abstract*: We study the existence and uniqueness for a path-dependent nonlinear Kolmogorov equation. The result is obtained by a stochastic approach, by proving a new type of nonlinear Feynman–Kac representation formula associated to a backward stochastic differential equation with time–delayed generator which is of non–Markovian type. The initiative is funded by the Research in Pairs project [ FBK-CIRM - https://cirm.fbk.eu/research-pairs ] “PATH DEPENDENT PARTIAL DIFFERENTIAL EQUATIONS WITH NONLINEAR BOUNDARY CONDITIONS” ( L. Di Persio, L. Maticiuc, A. Zalinescu ) __ Luca Di Persio - PhD College of Mathematics Dept. of Computer Science - University of Verona strada le Grazie 15 - 37134 Verona - Italy Tel : +39 045 802 7968 <http://www.hpa8.com/>

The usage of continuous time models allows us to manage irregularly spaced data (for example in financial time series due to weekends, holidays and breaks during the trading hours) without considering any missing data imputation method. Several routines for simulation and estimation are discussed. The flexibility of the package is due to the fact that the user is allowed to choose several parametric L\'evy distributions for the increments. Tutti gli interessati sono invitati a partecipare.
