QFinLab Seminar - Alessandro Sbuelz (Università Cattolica del Sacro Cuore) - 7/5/2025, 12:15 @ Department of Mathematics, Politecnico di Milano
by Alessandro Calvia 30 Apr '25

30 Apr '25

Dear colleagues, you are all invited to participate in the following seminar organized by QFinLab - Department of Mathematics, Politecnico di Milano. Wednesday, 7 May 2025, 12.15-13.15 Seminar room, third floor, building 14, Via Bonardi 9, Milano (Leonardo Campus) Alessandro Sbuelz (Università Cattolica del Sacro Cuore) Title: The Zero-Theta Hedge Contract. Abstract: We examine long-dated asset valuation under systematic and idiosyncratic risk, driven by extreme trajectories. By introducing the zero-Theta hedge contract, a negative-Delta derivative security with a maturity-independent price, we study investor attitudes toward systematic long-run crashes. Declining expected payoff with maturity signal strong crash aversion. The contract aids in decomposing the stochastic discount factor, shedding light on long-run crash risk premia. Even for volatile assets whose price comes from idiosyncratic rallies, systematic long-run crashes remain central to long-run risk valuation. Based on a joint work with Anna Battauz and Marzia De Donno. Next seminars: Olimpia Carradori (University of Zurich), 5 June 12.00. Marco Tolotti (Università Ca' Foscari Venezia), 9 June 12.15. All news can be found on the QFinLab webpage<https://www.qfinlab.polimi.it/seminars-and-meetings/>. The organizers: Michele Azzone and Alessandro Calvia.

Seminario Padova e Alumni Award - Jacopo Borga
by alekos.cecchin＠unipd.it 30 Apr '25

30 Apr '25

Buongiorno a tutti, Vorremmo segnalarvi che lunedì prossimo (5 Maggio) in aula 1BC45 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Jacopo Borga (MIT) <https://www.jacopoborga.com/> https://www.jacopoborga.com Title: Lattice Yang-Mills theory in the large N limit via sums over surfaces Date: May 5, 2025, at 14:30, room 1BC45 Abstract: Lattice Yang-Mills theories are important models in particle physics. They are defined on the d-dimensional lattice Z^d using a group of matrices of dimension N, and Wilson loop expectations are the fundamental observables of these theories. Recently, Cao, Park, and Sheffield showed that Wilson loop expectations can be expressed as sums over certain embedded bipartite maps of any genus. Building on this novel approach, we prove in the so-called strongly coupled regime: 1. A rigorous formula in terms of embedded bipartite planar maps of Wilson loop expectations in the large N limit, in any dimension d. 2. An exact computation of Wilson loop expectations in the large N limit, in dimension d=2, for a large family of (simple and non-simple) loops. Previous results to the two aforementioned points were established by Chatterjee (2019) and Basu & Ganguly (2016), respectively. Our results extend these previous results, offer simpler proofs and provide a new perspective on these significant quantities. This work is a collaboration with Sky Cao and Jasper Shogren-Knaak. Segnaliamo inoltre che Jacopo Borga terrà un seminario divulgativo e riceverà l'Alumni Special Award dell’Università di Padova lunedì, 5 maggio in aula 1A150, Torre Archimede Programma: * 16:30. Saluti istituzionali (Italian) * 16:40.

Short course by M. Gubinelli
by Lu Xu 29 Apr '25

29 Apr '25

Dear colleagues and friends, we are glad to announce the following short course in GSSI during May 12-16: ———————————————— The stochastic quantisation of the fractional $\Phi^4$ model in the full subcritical domain Lecturer: Prof. Massimiliano Gubinelli (University of Oxford) Venue: Main Lecture Hall, Gran Sasso Science Institute (Viale F. Crispi 7, L’Aquila) 13/5 (Mon) 14:15-15:45 14/5 (Tue) 16:15-17:45 15/5 (Wed) 10:45-12:15 16/5 (Thu) 10:45-12:15 I will present a complete proof of stochastic quantisation of a family of subcritical (i.e. superrenormalizable) scalar Euclidean QFT via the flow equation method of Duch. Euclidean QFT are measures on distributional fields which should be considered natural generalisation of Markov processes in higher dimension and which play a fundamental role in the rigorous construction of relativistic quantum fields. Stochastic quantisation is a method to realise such measures as pushforward of Gaussian measures via maps obtained by solving PDEs with random sources. In the last 10 years our understanding of the stochastic quantisation method has progressed greatly giving us new methods to attach the problems of EQFTs. The aim of the minicourse is to present, in most of the details, the various aspects of the construction of a particular class of EQFTs showcasing how probabilistic arguments merge with PDE estimates and renormalization group ideas. If the time permits I will also discuss the many open problems and fundamental issues in our understanding of these and more challenging models. ———————————————— Registration is free through the website: https://indico.gssi.it/event/745/. Other courses hosted by the trimester can be found in https://trimester2025.math.gssi.it/all_courses/. We would be grateful if you could circulate the announcement among potentially interested students and researchers. For any information do not hesitate to contact us (patterns(a)gssi.it<mailto:patterns@gssi.it>). With our best wishes, Lu Xu Assistant Professor (RTDb) Gran Sasso Science Institute
