Next LTI@Unito Seminar: Mihalis Zervos | April 29 @ 12:00 - 13:00
by Luca Regis 26 Apr '24

26 Apr '24

Dear Colleagues, please find below an invitation to the seminar that Mihail Zervos will give at Collegio Carlo Alberto (Torino) on April 29 from 12 to 13. The seminar can be attended via zoom, at the link below. Best, Luca Regis <https://4z5y5.r.sp1-brevo.net/mk/cl/f/sh/SMK1E8tHeFuBlzkcYLDa5hFz9Ao6/oGRQP…> LTI@UniTO and Fondazione Collegio Carlo Alberto are pleased to invite you to the following seminar: *April 29, 2024 | 12:00 - 13:00* *Market Equilibrium under Proportional Transaction Costs in a Stochastic Factor Model* *Mihalis Zervos (LSE)* *Abstract: *We consider an economy with two agents. Each of the two agents receives a random endowment flow. We model this cumulative flow as the stochastic integral of a deterministic function of the economy’s state, which we model by means of a general Ito diffusion. Each of the two agents has mean-variance preferences with different risk-aversion coefficients. The two agents can also trade a risky asset. We determine the agents’ optimal equilibrium trading strategies in the presence of proportional transaction costs. In particular, we derive a new free-boundary problem that provides the solution to the agents’ optimal equilibrium problem. Furthermore, we derive the explicit solution to this free-boundary problem when the problem data is such that the frictionless optimiser is a strictly increasing or a strictly increasing and then strictly decreasing function of the economy’s state.

PhD on Statistical mechanics on random graphs and algorithms
by Vanessa Jacquier 23 Apr '24

23 Apr '24

Inoltro per conoscenza. Dear colleagues, Please forward this information to any interested student. Thank you in advance! “PhD on Statistical mechanics on random graphs and algorithms” Job description Random spin systems from statistical mechanics have been successfully used to study critical behaviour at the interface of problems from mathematics, physics, biology and computer science. The measure describing the spin system gives the probability of likely configurations. Phase transitions occur when tuning a parameter of the system, in the sense that there are several Gibbs measures compatible with the microscopic interactions. In recent years, there has been enormous activity in order to study phase transitions for spin systems on random graphs by rigorously characterizing the set of Gibbs measures. Applications of such problems range from computational complexity, coding theory, to machine learning. This PhD project investigates statistical mechanics on random graphs and algorithms. The focus is on properties of the q-state Potts model, which is intimately related to random graph q-coloring and community detection problems. The project is a joint project between Prof. Remco van der Hofstad (TU/e), Dr. Noela Müller (TU/e) and Dr. Wioletta Ruszel (UU). Job requirements We are looking for a candidate that brings the following: a Master’s degree in mathematics; excellent English language and communication skills; knowledge of or affinity to physics and/or computer science is not required but considered an advantage; a demonstrable research-oriented experience, interest, or attitude. Conditions of employment A meaningful job in a dynamic and ambitious university, in an interdisciplinary setting and within an international network. You will work on a beautiful, green campus within walking distance of the central train station. In addition, we offer you: Full-time employment for four years, with an intermediate evaluation (go/no-go) after nine months. You will spend 10% of your employment on teaching tasks. Salary and benefits (such as a pension scheme, paid pregnancy and maternity leave, partially paid parental leave) in accordance with the Collective Labour Agreement for Dutch Universities, scale P (min. € 2.770,- max. € 3.539,-). A year-end bonus of 8.3% and annual vacation pay of 8%. High-quality training programs and other support to grow into a self-aware, autonomous scientific researcher. At TU/e we challenge you to take charge of your own learning process. An excellent technical infrastructure, on-campus children's day care and sports facilities.

School and conference in Bielefeld: "Gradient Flows, Large Deviation Theory, and Macroscopic Fluctuation Theory“
by Benjamin Gess 23 Apr '24

23 Apr '24

Dear colleagues, We would like to draw your attention to a School and conference on "Gradient Flows, Large Deviation Theory, and Macroscopic Fluctuation Theory“ which will take place *June 17-21 2024 at Bielefeld University* and is part of the 2024 activity month "Fluctuations in interacting systems: From optimal transport and Fokker–Planck equations to fluid dynamics and SPDEs“ of the collaborative research center 1283 ( https://www.sfb1283.uni-bielefeld.de/workshops/activitymonth/2024) The overarching topic of the conference is the effective description of large systems of interacting particles and their fluctuations around their typical behaviour. This mathematical challenge is of fundamental importance in a variety of applications, ranging from mathematical modelling in the sciences, to the foundations of non-equilibrium statistical mechanics and the dynamics of modern learning algorithms. Addressing these questions involves ideas from various disciplines in mathematics and physics. The workshop will bring together both leading experts and junior researchers from various fields, such as macroscopic fluctuation theory and non-equilibrium statistical mechanics, interacting particle systems, large deviation theory, gradient flows and variational methods for partial differential equations, and stochastic partial differential equations. The program will feature lecture series and talks by leading scientists as well as opportunities for junior scientists to present their work. For more details please see https://www.sfb1283.uni-bielefeld.de/2024_MFT/ With kind regards, Matthias Erbar and Benjamin Gess -- Prof. Dr. Benjamin Gess (www.bgess.de) Universität Bielefeld <https://www.math.uni-bielefeld.de/>, Fakultät für Mathematik Max Planck Institute for Mathematics in the Sciences <http://www.mis.mpg.de/index.html>, Leipzig

OWABC - Francesca Crucinio - 2nd May 2024 9am
by Massimiliano Tamborrino 23 Apr '24

23 Apr '24

Dear all, our next OWABC seminar www.warwick.ac.uk/oneworldabc<http://www.warwick.ac.uk/oneworldabc> is quickly approaching. We are happy to announce that our next speaker is Francesca Crucinio (King's College London), who will talk about "A connection between Tempering and Entropic Mirror Descent" on Thursday the 2nd May, 9am UK time. Abstract: This work explores the connections between tempering (for Sequential Monte Carlo; SMC) and entropic mirror descent to sample from a target probability distribution whose unnormalized density is known. We establish that tempering SMC corresponds to entropic mirror descent applied to the reverse Kullback-Leibler (KL) divergence and obtain convergence rates for the tempering iterates. Our result motivates the tempering iterates from an optimization point of view, showing that tempering can be seen as a descent scheme of the KL divergence with respect to the Fisher-Rao geometry, in contrast to Langevin dynamics that perform descent of the KL with respect to the Wasserstein-2 geometry. We exploit the connection between tempering and mirror descent iterates to justify common practices in SMC and derive adaptive tempering rules that improve over other alternative benchmarks in the literature.

Korba, A connection between Tempering and Entropic Mirror Descent, Preprint at ArXiv: 2310.11914<https://arxiv.org/pdf/2310.11914.pdf> The talk will be streamed on MS Teams at this link https://teams.microsoft.com/l/meetup-join/19%3ameeting_YTNiMmNkZTUtYTI4Mi00… Meeting ID: 378 951 648 902 Passcode: YB8fb5 We are looking forward to seeing you on May 2, best, Massimiliano on the behalf of the OWABC Seminar organisers ------ Dr. Massimiliano Tamborrino Associate Professor and Warwick International Higher Education Academy (WIHEA) Fellow Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino
