Secondo ciclo di seminari online sulle applicazioni della probabilità in economia: Sara Biagini
by Enrico Scalas 21 Sep '26

21 Sep '26

Buongiorno, ecco l'annuncio e il link per il terzo e ultimo seminario della serie per quest'anno. Speaker: Sara Biagini, Department of AI, Data and Decision Sciences, LUISS Date: 25 September 2026, 2:00 PM Title: An introduction to carbon markets regulation: carbon neutrality and Net-Zero Abstract: After introducing carbon markets, we analyze the impact of carbon dioxide regulation on a system of polluting, heterogeneous companies. We consider two compliance frameworks: one based on an emission trading system (ETS) mechanism and the other relying only on abatement efforts. The shocks in the economy are spanned by a multivariate Brownian motion, and the companies’ emissions are modeled as general diffusions. Firms must match their projected emission imbalance with their reduction effort at the compliance date in both frameworks. Under the ETS program, to do so firms can both abate and trade carbon permits in the ETS permits exchange. Existence and uniqueness of the optimal abatement and trade, together with the equilibrium carbon price, are proven under mild necessary and sufficient conditions. The optimizers and the carbon price are explicit, and their analytic expressions provide an instance of classic economic principles. Numerical examples illustrate the flexibility of the model in the study of the effect of significant allocation policies. Under the net-zero framework, firms can only rely on abatement, which is also provided in closed-form. link: https://polimi-it.zoom.us/j/92441911901 backup link: https://teams.microsoft.com/meet/320979871582913?p=m9GlxMBKHZBCdbzitS Cordiali saluti, Giulio Bottazzi, Alessandro Calvia, Marco Capaldo, Enrico Scalas

Next Webinar PRISMA - Oct 6, 2026 - Speakers: M. Stecconi & A. P. Todino
by Maurizia Rossi 21 Sep '26

21 Sep '26

Webinar of the team UMI - PRISMA (http://www.umi-prisma.polito.it/) PRISMA webinars follow a colloquium-style format designed to foster exchange and discussion within the Italian probability and statistics community. Each session features two speakers, who give two closely connected 30-minute talks providing the community with a perspective on their research area. Over the past few years, recordings of the seminars have been made available on the UMI YouTube channel: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb The next event is scheduled for *Tuesday, Oct 6, 2026*. The speakers will be *Michele Stecconi* (Université du Luxembourg) and *Anna Paola Todino* (Università del Piemonte Orientale), who will speak on: *Statistics on Yau's conjecture: variance asymptotics and Wiener-Itô chaos decomposition for Gaussian nodal volumes* according to the following schedule *16:00 Stecconi* (Statistics on Yau’s conjecture: variance asymptotics) 16:30 Break and discussions *16:45 Todino* (The Wiener-Itô chaos decomposition for Gaussian nodal volumes) 17:15 Conclusions and discussions The *abstract* can be found below. The seminars will be streamed on *Webex* at the following link: https://unimib.webex.com/unimib-it/j.php?MTID=mad4e0bc0268687d5172a5217fffb… Numero Riunione: 2744 110 0273 Password Riunione: Abu39JQkaQ4 We look forward to seeing many of you there! Luciano Campi, Maurizia Rossi *Abstract (Stecconi). *Yau's conjecture predicts that the nodal set (the set of zeroes) of a Laplace eigenfunction on an n-dimensional compact Riemannian manifold has volume proportional to the frequency. Berry's conjecture suggests a statistical viewpoint: at high frequency, eigenfunctions should look locally like monochromatic random waves. We give Yau's conjecture a probabilistic formulation and study how much the nodal volume of a random wave fluctuates around the predicted value, depending on the spectral window. For wide windows, of size proportional to the frequency, the variance has exactly the order 1/N, where N is the number of eigenfunctions in the window, on every manifold. For the monochromatic window, on manifolds without conjugate points (negatively curved ones, for instance), we obtain an upper bound smaller than the square of the best one previously known. This improvement reveals that Berry's cancellation holds on such manifolds: the nodal volume of monochromatic waves fluctuates strictly less than it does for wider ones, and strictly less than the volume of any non-zero level set. The proofs rely fundamentally on a new Wiener chaos decomposition of nodal volumes, discussed in the subsequent talk. *Abstract (Todino). *Analyzing the fluctuations of Gaussian zero sets often requires decomposing the nodal volume into orthogonal components known as Wiener-Itô chaos. Historically, this approach has suffered from severe computational complexity, especially in high dimensions, restricting its applicability to highly symmetric spaces. In this talk, we introduce a new, remarkably simpler formula for the chaos expansion of smooth Gaussian fields on arbitrary Riemannian manifolds. We will show how this new perspective drastically reduces the complexity of variance computations, moving from products of many Hermite polynomials to just four, and removes isotropy requirements. -- Maurizia Rossi Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca https://mauriziarossi.wordpress.com

SPASS seminar: Matteo Palmieri - Tue 22 Sept
by Lorenzo Marino 18 Sep '26

18 Sep '26

Dear Colleagues, We are pleased to invite you to the following SPASS seminar https://sites.google.com/unipi.it/spass/seminars?authuser=0 <https://sites.google.com/unipi.it/spass/seminars?authuser=0%3E> (jointly organised by UniPi, SNS, UniFi and UniSi): Speaker: Matteo Palmieri (Max Planck Institute, Leipzig, Germany) Title: A geometrically linear approximation of min-max optimal matching Date and time: Tuesday, September 22th at 14:00 CET Place: Aula Bianchi Scienze, Palazzo della Carovana, Scuola Normale Superiore, Pisa Abstract: In this talk, I will present a connection between min-max optimal matching and a certain isoperimetric problem with a random volume term with white-noise character. The former is the discrete combinatorial optimization task of finding the matching between two random point clouds, which is optimal in the sense that it minimizes the maximum distance between coupled points. The latter, in its additive form, can be interpreted as an isotropic version of the random-field Ising model at zero temperature. Both problems are critical in two dimensions and scale like the power 3/4 of the number of exponential scales involved. Relying on ideas from the regularity theory of minimal surfaces, in the second problem one may replace the perimeter by the Dirichlet energy. This defines a geometrically linearized, simpler, (1+1)-dimensional action, which enjoys an additional scaling invariance and allows us to identify the leading-order constant of the two optimal values. This is based on joint work with Xiaopeng Cheng, Felix Otto, Arthur Wachtel and Christian Wagner.

Seminar by R. van der Hofstad at Milano-Bicocca (25 September)
by Francesco Caravenna 18 Sep '26

18 Sep '26

I am pleased to announce the following seminar at Milano-Bicocca: Remco van der Hofstad (Eindhoven University of Technology) The number and structure of connected graphs with a fixed degree sequence Friday, 25 September at 14:00 Room U9-08 (Building U9, Viale dell'Innovazione 10, Milano) Streaming (WebEx): link <https://unimib.webex.com/unimib-it/j.php?MTID=m231eb8e5e4a064481de4a585b6be…> The abstract follows below. Everyone interested is welcome. Best regards, Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%% Abstract. We study connected graphs with a fixed degree sequence, in the sparse setting where the number of edges grows linearly in the number of vertices. Using the relation to the configuration model, we identify the number of such connected graphs up to a subexponential order. We do this by viewing a connected graph with a given degree distribution as the realization of the giant component in a larger configuration model, and carefully choosing the degree distribution of the larger graph so that it is likely that its giant component has the required degree distribution. To ensure that the connected graph has exactly the correct degrees, we use a switching argument. We further identify the local structure of a uniform random graph with prescribed degrees. This is joint work with Sasha Bell and Serte Donderwinkel. Possibly I will also touch upon work with them and Luisa Andreis. %%%%%%%%%%%%%%%%%%%%%%%%%% -- __________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca https://fcaraven.github.io/ __________________________________
