Seminar Announcement @CCA June 27th: Lorenzo Schoenleber
by Luca Regis 24 Jun '22

24 Jun '22

Dear Colleagues, I am pleased to invite you to the following seminar in Quantitative Finance by Lorenzo Schoenleber (CCA), which will take place at Collegio Carlo Alberto (Torino) and online at the Zoom link below on Monday, June 27th, 12.00. Best regards, Luca Regis Speaker: Lorenzo Schoenleber (CCA) Title: Manoeuvring and Investing in Yield Farms Abstract: This paper is about Yield Farming which denotes a DeFi strategy of seeking rewards in the form of transaction fees by depositing tokens into a decentralized application. We demystify the investment process and quantify transaction costs, returns, and risks using historical data from a major DEX. We reveal the economic mechanisms providing a mathematical (optimization) framework which resembles the yield farming investment process including the direct modeling of returns, transaction costs, and sources of risk.

One World ABC Seminar - Cosma Shalizi - 23 June - 1.30pm UK time
by Massimiliano Tamborrino 20 Jun '22

20 Jun '22

Dear all, our next and last One World ABC seminar <https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwarwick.a…> of the season is quickly approaching. On Thursday June 23, at 1.30pm UK time, Cosma Shalizi<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.stat.…> will talk about "Matching Random Features", with an abstract reported below. The Zoom link to join the talk is https://bristol-ac-uk.zoom.us/j/99993089580?pwd=NUtzT0VLdGNvb0tJMFRNMXl6SlN…<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbristol-a…> Password: 486380 We are looking forward to seeing you on Thursday, best wishes, Massimiliano on the behalf of the One World ABC Seminar Organisers Speaker: Cosma Shalizi<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.stat.…>, Carnegie Mellon University Title: Matching Random Features Abstract: We can do statistical inference on simulation models by adjusting the parameters in the simulation so that the values of randomly chosen functions of the simulation output match the values of those same functions calculated on the data. Results from the ”statespace reconstruction” or “geometry from a time series” literature in nonlinear dynamics indicate that just 2d + 1 such functions will typically suffice to identify a model with a d-dimensional parameter space. Results from the “random features” literature in machine learning suggest that using random functions of the data can be an efficient replacement for using optimal functions. In this talk, I sketch some of the key results, present numerical evidence about the new method’s properties, and lay out an agenda for research. Reference: C. Shalizi.

Seminar in Pisa: Leonardo Maini
by Francesco Grotto 20 Jun '22

20 Jun '22

Dear Colleagues, we would like to invite you to the following seminar by Leonardo Maini (Université du Luxembourg) to be held Wednesday, June 22nd, in Aula Contini, at Scuola Normale Superiore in Pisa. The seminar will take place in full presence (speaker included), but it will be streamed via Google Meets, link below. The organizers, A. Agazzi and F. Grotto -------------------------------------------- Location: *Aula Contini*, Scuola Normale Superiore, Pisa Google Meet Link: https://meet.google.com/gji-phwo-vbg Time: June 22nd 2022, 14:00-15:00 CET Speaker: Leonardo Maini (Université du Luxembourg) Title: Spectral central limit theorem for additive functionals of Gaussian fields Abstract: We consider a centered, continuous, stationary, Gaussian field on the Euclidean space and a sequence of non-linear additive functionals of the field. Since the pioneering works from the 80s by Breuer, Dobrushin, Major, Rosenblatt, Taqqu and others, central and non-central limit theorems for this kind of functionals have never ceased to be refined. The common intuition is that the limit is Gaussian when we have short-memory and non-Gaussian when we have long-memory and the Hermite rank R is different from 1. Our goal is to show that this can be a misleading intuition. To do that, we introduce a spectral central limit theorem, which highlights a variety of situations where the limit is Gaussian in a long-memory context with R different from 1. Our main mathematical tools are the Malliavin-Stein method and Fourier analysis. The talk is based on a joint work with Ivan Nourdin (University of Luxembourg).
