Assegno di ricerca presso il Dipartimento di Scienze Chimiche (Gruppo di Chimica Teorica), Università di Padova Research fellowship at the Department of Chemical Sciences (Theoretical Chemistry Group), University of Padova ·*Progetto PNRR / PNRR Project*: CN HPC Spoke 1 ·*Durata dell’assegno / Duration of the fellowship*: 12 mesi / months ·*Selezioni / Selections*: 22.08.2023 ·*Inizio dell’assegno / Felloship starts in*: settembre o ottobre 2023 / september or october 2023 ·*Lordo percipiente / gorss amount*: 19367.00 Euro ·*Titolo/Title* Strategie meshless ottimizzate tramite machine learning per la soluzione di equazioni stocastiche in molti gradi di libertà Machine learning-optimized meshless strategies for the solution of stochastic equations in many degrees of freedom ·*Progetto/Project* L’assegnista si occuperà dello sviluppo e dell’implementazione di un software per risolvere equazioni stocastiche in molti gradi di libertà, in particolare ottimizzandolo su GPU o architetture hardware simili, ossia che permettano una parallelizzazione estesa su singola scheda. La strategia di risoluzione si baserà su tecniche meshless, dato che il software dovrà essere in grado di affrontare problemi con O(10-100) gradi di libertà. Per ridurre il costo computazionale sarà necessario stabilire la miglior scelta (adattiva) dei punti su cui rappresentare la soluzione dell’equazione. A tale scopo, tecniche di machine learning potranno sfruttare la costruzione iterativa della soluzione sia per accelerare il processo stesso, sia per definire la miglior distribuzione di punti. The research fellow will be responsible for the development and implementation of a software package able to solve stochastic equations in many degrees of freedom. The software should be optimized for GPUs or similar hardware architectures that allow for extensive parallelization on a single board. The resolution strategy will be based on meshless techniques since the software needs to be able to handle problems with O(10-100) degrees of freedom. To reduce the computational cost the optimal (adaptive) choice of points for representing the solution of the equation must be determined. To this purpose, machine learning techniques can be used to exploit the iterative construction of the solution, both to speed up the process itself and to define the best distribution of points. ·*Link (dal / from 13.07.2023 al / to 28.07.2023)*: https://www.dei.unipd.it/node/43362 <https://www.dei.unipd.it/node/43362> -- Prof. Marco Ferrante Prorettore alla Didattica Vice-Rector for Teaching and Education Dipartimento di Matematica "Tullio Levi-Civita" Università degli Studi di Padova Via Trieste 63 , I-35121 Padova - ITALY Tel: +39-0498271366 Fax: +39-0498271499 E-Mail:ferrante@math.unipd.it URL:http://www.math.unipd.it/~ferrante

AVVISO di SEMINARIO Prof. CLAUDIO MACCI Dipartimento di Matematica, UNIVERSITÀ Tor Vergata, ROMA TITLE Non-central moderate deviations for compound fractional Poisson processes Abstract The term moderate deviations is often used in the literature to mean a class of large deviation principles that, in some sense, fills the gap between a convergence in probability to zero (governed by a large deviation principle) and a weak convergence to a centered Normal distribution. We talk about non-central moderate deviations when the weak convergence is towards a non-Gaussian distribution. In this paper we study non-central moderate deviations for compound fractional Poisson processes with light-tailed jumps. Joint work with Luisa Beghin. Il seminario si terrà il giorno 12 LUGLIO 2023 ore 16:00 nella Aula E del Dipartimento Matematica e Applicazioni, Università di Napoli FEDERICO II, Complesso di Monte Sant'Angelo, Via Cintia, Napoli.

AVVISO di SEMINARIO Prof. ENRICO SCALAS School of Mathematical and Physical Sciences of SUSSEX UNIVERSITY TITLE A fractional Hawkes process Abstract A Hawkes point process with kernel proportional to the probability density function of Mittag- Leffler random variables is introduced. This kernel decays as a power law with exponent $\beta+1 \in (1,2]$. Several analytical results are proved, in particular for the expected intensity of the point process and for the expected number of events of the counting process. These analytical results are used to validate algorithms that numerically invert the Laplace transform of the expected intensity as well as Monte Carlo simulations of the process. Finally, Monte Carlo simulations are used to derive the distribution of the number of events. The algorithms used for this presentation are available at https://github.com/habyarimanacassien/Fractional-Hawkes Relevant papers: Chen, J, Hawkes, A G and Scalas, E (2021) A fractional Hawkes process.

Seminar Barbara Vantaggi in Bologna
by Sabrina Mulinacci 06 Jul '23

06 Jul '23

Dear alla we are glad to announce the seminar of Barbara Vantaggi at the Department of Statistical Sciences of the University of Bologna The seminar is today July 6th 2023 at 4 pm. A dynamic Choquet pricing rule with bid-ask spreads under ambiguity We introduce a dynamic pricing rule allowing for frictions in the form of bid-ask spreads, by modeling “risk-neutral” uncertainty through belief functions. The aim is to face pricing in a multi-period binomial market model under ambiguity. To this purpose, we introduce and characterize Dempster-Shafer multiplicative binomial processes together with the induced conditional Choquet expectation operator. Next, we consider a market formed by a frictionless risk-free bond (whose price is modeled by a deterministic process) and a non-dividend paying stock with frictions (whose lower price is modeled by a Dempster Shafer multiplicative binomial process). In this market we prove an analog of the classical theorem of change of measure relying on the notion of equivalent one-step Choquet martingale belief function. We then propose a dynamic Choquet pricing rule with bid-ask spreads showing that the discounted lower price process of a European derivative contract on the stock is a Choquet super-martingale. We also provide a normative justification in terms of a dynamic generalized no-arbitrage condition. We finally discuss the connections of the introduced dynamic pricing rule with time-consistency and dynamic risk measures. The talk is based on papers in collaboration with A.Cinfrignini and D.
