SPASS Seminar: Lucie Laurence
by Andrea Agazzi 23 Nov '23

23 Nov '23

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Scaling methods for stochastic chemical reaction networks * by Lucie Laurence (INRIA Paris) The seminar will take place on TUE, 28.11.2023 at 14:00 CET in Aula Seminari, Dipartimento di Matematica, UNIPI and streamed online at the link below. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract: **In this talk we investigate stochastic chemical reaction networks (CRNs) with scaling methods. This approach is used to study the stability properties of the associated Markov processes, but also to investigate the transient behavior of the sample paths. It also gives insight on the impact of specific features of these networks such as their polynomial reaction rates, leading to the coexistence of multiple timescales. Some examples of CRNs are discussed to illustrate the multiple timescales involved in the decay of the norm of the state when the CRN starts from a “large” initial state. A detailed scaling analysis of an interesting CRN exhibiting a slow decrease of the norm of the state is presented.*

Fwd: Seminario Padova - Dario Trevisan
by Alekos Cecchin 21 Nov '23

21 Nov '23

Buongiorno a tutti, Vorremmo segnalarvi che questo venerdì (24 Novembre) alle ore 14:30 in aula 1BC50 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: *Dario Trevisan* (Università di Pisa) *Title*: On the Concave One-Dimensional Random Assignment Problem: Kantorovich Meets Young *Date*: November 24, 2023 at 14:30, room 1BC50, Torre Archimede, Padova *Abstract*: We consider the assignment (or bipartite matching) problem between n source points and n target points on the real line, where the assignment cost is a concave power of the distance, |x-y|^p, for 0<p<1. It is known that, differently from the convex case (p>1) where the solution is rigid, i.e. it does not depend on p, in the concave case it may varies with p and exhibit interesting long-range connections, making it more appropriate to model realistic situations, e.g. in economics and biology. In the random version of the problem, the points are samples of i.i.d. random variables, and one is interested in typical properties as the sample size n grows. Barthe and Bordenave in 2013 proved asymptotic upper and lower bounds in the range 0<p<1/2, which they conjectured to be sharp. Bobkov and Ledoux, in 2020, using optimal transport and Fourier-analytic tools, determined explicit upper bounds for the average assignment cost in the full range 0<p<1, naturally yielding to the conjecture that a "phase transition" occurs at p=1/2. We settle affirmatively both conjectures. The novel mathematical tool that we develop, and may be of independent interest, is a formulation of Kantorovich problem based on Young integration theory, where the difference between two measures is replaced by the weak derivative of a function with finite q-variation. Joint work with M. Goldman (arXiv:2305.09234). Vi aspettiamo numerosi! Alberto Chiarini e Alekos Cecchin

L'argomento è l'analisi di dati medici (prevalentemente immagini, ma non solo) per inferenza su variabili predittive della salute futura del paziente (speranza di vita, probabilità di fratture, e altro). Il tema di ricerca è descritto con qualche dettaglio in più qui (assegno #14): https://www.unich.it/sites/default/files/scheda_1declaratoria_assegni_2.pdf. Background in questo tipo di analisi è benvenuto, ma non necessario, perché è previsto un periodo iniziale di formazione sull'argomento.

Announcement: Quantum Computing for Finance – Course by Prof. Jacquier - 04.12-07.12.2023
by Viktoria Schildhammer 21 Nov '23

21 Nov '23

Dear colleagues, We would like to announce the following course: “Quantum Computing for Finance” held by Professor Antoine Jacquier taking place at the University of Vienna, at the department for Statistics and Operations Research at Kolingasse 14-16, 1090 (https://quarimafi.univie.ac.at/quantum-computing-finance/). The course will take place from Monday, 04.12.2023, until Thursday, 07.12.2023. It is aimed at PhD students and researchers who want to get acquainted with quantum computing and its potential applications in the finance . Please find the preliminary program for the course here: https://quarimafi.univie.ac.at/quantum-computing-finance/programm/. The abstract of the course and a short bio of Antoine Jacquier can be found below and on the website. Attending the course is for free, but please register via email to <viktoria.schildhammer(a)univie.ac.at>. The registration deadline is the 30.11.2023. This is the last day where registrations will be accepted. Please also mention in your registration email your full name and affiliation! In case of problems / questions, please do not hesitate to send us an e-mail! We are looking very much forward to welcoming you at the course! Kind regards, Prof. Christa Cuchiero and Viktoria Schildhammer ------------------------------- Abstract: Quantum Computing, relegated for decades as a spooky distant myth, is now becoming a reality. To wit, quantum computers (albeit small in scale) are already available, developed by the likes of IBM, Rigetti, D-Wave, Google, Microsoft, ..... However, a quantum computer is not simply a bigger and more powerful computer, and requires a whole new set of algorithms to be written to perform useful tasks. These, and the underlying technology, draw from the laws of quantum mechanics, fundamentally different from our usual numerical toolbox. The goal of this course is to provide a mathematical introduction to Quantum Computing and to highlight applications in Quantitative Finance, in particular for Monte Carlo simulations, machine learning and optimisation. Numerical examples (through python) will also be introduced to provide a tangible reality. Bio: Antoine Jacquier is Professor of Mathematics in the Department of Mathematics at Imperial College London. His research interests range from Probability Theory and Stochastic Analysis to Numerical Analysis and Quantum Computing, with a view towards applications in Mathematical Finance. For more details on his research or his published papers, please visit his homepage: https://jackantoinejacquie.wixsite.com/jacquier.
