Virtual Seminar by M. Grigorova (Leeds)

01 Nov '21

Dr. Miryana Grigorova (University of Leeds) will give a talk organized by the Department of Economics - University of Verona Date: 3 November 12:00 CET. Title: "Superhedging of options in a non-linear incomplete financial market model” Abstract: We will study the superhedging price (and superhedging strategies) of European and American options in a non-linear incomplete market model with default, with a particular focus on the American options case which is more involved. We will provide a dual representation of the seller’s (superhedging) price for the American option in terms of a mixed stochastic control/stopping problem with non-linear expectations/ evaluations, and in terms of non-linear Reflected BSDEs with constraints. If time permits, we will also present a duality result for the buyer’s price in terms of a stochastic game of control and stopping with non-linear expectations/ evaluations. The talk is based on joint works with Marie-Claire Quenez and Agnès Sulem. If you would like to attend via Zoom, please register at the following link, we will send you the details: https://docs.google.com/forms/d/e/1FAIpQLScVu88XwBhoF9O3xmbKwUxv0JN2URNT3Ki… -- Prof Alessandro Gnoatto, PhD Dipartimento di Scienze Economiche Università degli Studi di Verona Via Cantarane 24 37129, Verona, Italy Room 1.05 Tel: +39 045 802 8537 Homepage: www.alessandrognoatto.com E-mail: alessandro.gnoatto(a)univr.it -------------------------------------------------- View my research on my SSRN Author page: http://ssrn.com/author=1615989 --------------------------------------------------

Assegno di ricerca a Tor Vergata
by mic sal 28 Oct '21

28 Oct '21

Cari colleghi, vi segnalo un bando per assegno di collaborazione della durata di 1 anno presso l'Università di Roma "Tor Vergata". La data di scadenza per la presentazione delle domande è prevista per il 3/11. Il bando è reperibile al sito pica.cineca.it immettendo come chiavi di ricerca il codice del bando F3-2021-0014 e l'ente/istituzione Università degli Studi di Roma "Tor Vergata" In fondo a questo messaggio, allego il titolo del progetto di ricerca e la sua descrizione sintetica. Sono benvenute candidature con profili in un qualsiasi ambito della matematica applicata, purché prevedano delle applicazioni computazionali da sviluppare durante l'anno di collaborazione all'attività di ricerca. Esse dovranno essere svolte con le risorse di calcolo messe a disposizione del dipartimento di matematica dell'Università di Roma "Tor Vergata". Qualora il/la candidato/a vincitore/trice abbia già lavorato in meccanica celeste / sistemi dinamici Hamiltoniani / astrodinamica, potrà collaborare con il prof. Ugo Locatelli, il quale è formalmente responsabile del bando. Altrimenti, se sarà principalmente esperto/a in altre aree della matematica applicata, sarà possibile scegliere un altro qualsiasi docente del Dipartimento, che assumerà le funzioni di principale collaboratore/trice del/la futuro/a vincitore/trice della procedura di selezione. Cordiali saluti, Michele Salvi %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Titolo del progetto di ricerca "New Computational Challenges in Applied Mathematics" Descrizione sintetica della ricerca In the last decades, the fast increase of the computational resources opened the possibility to tackle new fascinating problems in mathematics. This recent development is concerning both the hardware and the software. From one hand, the total computational power has been enormously increased by codes that can be efficiently parallelized on GPGPU cards and/or in multi-core environments. On the other hand, in computer science new paradigms have shown their effectiveness: e.g., machine learning has been applied in several different contexts. The candidates are expected to be able to autonomously develop a high-level research with computational applications in at least one field of the following (non-exhaustive) list: dynamical systems, simulations in ODEs/PDEs, high-dimensional statistical analysis. The transfer of knowledge will be strongly encouraged also with exposure to activities of (active and passive) training.

---------- Forwarded message ---------- Date: Mon, 25 Oct 2021 14:27:29 +0200 From: grassell(a)math.unipd.it To: vargiolu(a)math.unipd.it Subject: Annuncio Seminario Johannes Ruf Caro Tiziano potresti estendere alla tua lista l'annuncio del seguente seminario please ? Verr? tenuto in presenza con possibilit? di seguirlo via zoom. Grazie mille Martino --------------------------------- On Tuesday Nov 2 at 11am the Math Department of the University of Padua is pleased to host a seminar given by Prof. Johannes Ruf (LSE University, London). Here below the relevant details: WHEN: November 2, at 11:00am WHERE: Room 2BC30 at 2nd floor of the Math Department "Tullio Levi-Civita", via Trieste 63, Padua ZOOM link: https://unipd.zoom.us/j/83202006980 (without password) SPEAKER: Johannes Ruf TITLE: The Growth-Optimal Portfolio in Fund Models ABSTRACT: This study concerns the estimation of the growth-optimal portfolio. The growth-optimal portfolio, or the numeraire portfolio, maximises the expected logarithmic growth rate and plays a fundamental role in portfolio choice and asset pricing. Efficient estimates of the growth-optimal portfolio under the CAPM and multi-fund models are derived. The accuracy of estimation is greater, the larger the variances of the returns. A measure of investors' economic loss caused by information loss due to missing data or unavailable observations is provided. In particular, the economic loss is larger, the larger the investment universe or the factors affecting asset returns. The estimate has a Bayesian interpretation. A shrinkage method targets maximal growth with the least amount of deviation of the growth rates.
