Abstract: We compute quantitative bounds for measuring the discrepancy between the distribution of two min-max statistics involving either pairs of Gaussian random matrices, or one Gaussian and one Gaussian-subordinated random matrix. In the fully Gaussian setup, our approach allows us to recover quantitative versions of well-known inequalities by Gordon, thus generalising the quantitative version of the Sudakov-Fernique inequality deduced by Chatterjee. On the other hand, the Gaussian-subordinated case yields generalizations of estimates obtained in the framework of the CCK theory. As applications, we establish comparison bounds for order statistics of random vectors and fourth moment bounds for matrices of multiple stochastic Wiener-Itô integrals. Based on a joint work with G. Peccati.

*Abstract: *We introduce a natural measure on bi-infinite random walk
trajectories evolving in a time-dependent environment driven by the
Langevin dynamics associated with a gradient Gibbs measure with convex
potential. We derive an identity relating the occupation times of the
Poissonian cloud induced by this measure to the square of the corresponding
gradient field, which - generically - is not Gaussian. In the quadratic
case, we recover a well-known generalization of the second Ray-Knight
theorem. We further determine the scaling limits of the various objects
involved in dimension 3, which are seen to exhibit homogenization. In
particular, we prove that the renormalized square of the gradient field
converges under appropriate rescaling to the Wick-ordered square of a
Gaussian free field on R^3 with suitable diffusion matrix, thus extending a
celebrated result of Naddaf and Spencer regarding the scaling limit of the
field itself. (Based on joint work with Pierre-François Rodriguez.)

Dear All,
it is a pleasure to announce the
Summer School on “Replicability crisis in science?”
University of Padova, Italy, 18-22 September 2023
The school is open to 30 Ph.D or Master students, no fees are required,
but registration is mandatory. Lectures will be delivered in English.
Main Lecturers:
Prof. Giovanni Parmigiani, Department of Data Science, Dana Farber
Cancer Institute, Harvard University, USA
(https://scholar.harvard.edu/parmigiani)
Prof. Branden Fitelson, Department of Philosophy and Religion,
Northeastern University, USA
(https://cssh.northeastern.edu/faculty/branden-fitelson/)
Course Outline:
The main objective of the Summer School is to offer to a well-motivated
small group of young people starting their scientific research journey
an opportunity for high-level interdisciplinary training on crucial
issues arising from the recent debate concerning the crisis of
replicability in scientific research.
The school will provide a broad and interdisciplinary view, as well as
the tools that may enable individual participants to focus on specific
aspects of replicability that are relevant to their own discipline of
interest.
Activities will include both main lectures and lab sessions for Master
and Ph.D. students coming from different countries.
The lectures will offer to participants a set of theoretical and
applied tools to conduct and critically evaluate rigorous research. In
workshop activities, students will have the opportunity to discuss the
topics with both teachers and peers in order to overcome traditional
boundaries between statistics and philosophy and other sciences as well
as to stimulate innovative research hypotheses and international
collaborations.
Conference Website:
http://replicability.stat.unipd.it/
Registration:
application is now open until 31 May 2023. Participants will be selected
based on their CV, motivation letter, research interests, and balance
within the group in terms of gender and geographical origin.
Notification of decisions will be sent to applicants via email by 30
June 2023.
Organizers:

Dear all of the SMAQ group,
this is to announce that Daniel Ueltschi will give a Colloquium talk at
GSSI on
*Loop models and the universal distribution of the loop lengths*
this Thursday*, May 4th, 2023 at 14.00 in the **GSSI Auditorium (please
NOTICE the unusual time).*
The talk will be also streamed online at the link below:

Passcode: MATHatGSSI
Abstract. I will review several models that consist of one-dimensional
loops living in the three-dimensional space. These models describe bosonic
systems, and classical or quantum spin systems. Their common feature is
that the joint distribution of their loop lengths has universal behaviour:
It is always a Poisson-Dirichlet distribution. Most of this theory is
conjectural, but it is backed by numerical studies and some partial
rigorous results.
Best,
Serena

Dear colleagues,
we are happy to announce the hybrid - that is, in person with online streaming - talk of the (PMS)^2 series:
Speaker: Davide Addona (Università di Parma)
Title: Young equations in infinite dimension with singularities.
Abstract: In this talk I will present some new results about Young differential equations in infinite dimension with “non smooth” initial datum. During the talk I will introduce the concept of Young integral for non smooth paths defined by Young in 1936 and an algebraic approach to integration with respect to non smooth paths due to Gubinelli in 2004, whose generalization allows to consider abstract Cauchy problems driven by an irregular path. At last, if I will have time, I will give an idea of the of the theory of rough paths started by Terry Lions in 1998 and developed by other authors in the last twenty years.
Date and time: Monday May 8, 16:30-17:30 (Rome time zone).
Place: Aula Seminari - III piano (third floor), Dipartimento di Matematica, Politecnico di Milano, Piazza Leonardo da Vinci, 32 – 20133 Milano - Ed. 14 “Nave” Campus Bonardi.

Dear Colleagues,
We would like to invite you to the following SPASS seminar, jointly
organized by UniPi, SNS, UniFi and UniSi:
Random currents and homologies on compact manifolds
Mauro Mariani (National Research University Moscow)
The seminar will take place on TUE, 9.5.2023 at 14:00 CET in Sala Seminari,
Dipartimento di Matematica, Pisa 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: *
We study the long time behavior of stochastic currents associated to
diffusion processes on compact Riemannian manifolds. In the first part of
the talk, sharp results about existence and tightness of stochastic
currents will be discussed.
In the second part, some problems related to random homologies (homology
class associated to the paths of diffusion processes) will be addressed. In
particular, we give a full geometric characterization of manifolds such
that the associated random homology has a gaussian asymptotic. Some simpler
related problems (Gallavotti-Cohen symmetry, relation with the Riemannian
metric).
Salve,
ricevo e inoltro con preghiera di diffusione.
Cordialmente,
m.gianfelice
