*Title*: Non-local differential operators in probability
*Abstract*
The study of nonlocal differential operators is an active field of research
in pure and applied mathematics and has been drawing increasing attention
over the last few years. Fractional-order operators (i.e. integrals and
derivatives of non-integer order) are maybe the most famous and studied in
the literature. Their origin goes back to the end of the seventeenth
century, but only recently they have been applied to a variety of fields
ranging from biology to engineering, probability theory, physics, image
processing among others. In this talk, we will concentrate our attention on
the stochastic applications of non-local operators, in particular in the
theory of anomalous diffusions and renewal processes.

*Title*: On the Correlation of Critical Points and Angular Trispectrum for
Random Spherical Harmonics.
*Abstract*
We prove a Central Limit Theorem for the Critical Points of Random
Spherical Harmonics, in the High-Energy Limit. The result is a consequence
of a deeper characterizations of the total number of critical points, which
are shown to be asymptotically fully correlated with the sample
trispectrum, i.e., the integral of the fourth Hermite polynomial evaluated
on the eigenfunctions themselves. As a consequence, the total number of
critical points and the nodal length are fully correlated for random
spherical harmonics, in the high-energy limit.

Titolo: Bayesian non-stationary spatial modeling via domain partitioning, with application to soil organic carbon
Abstract: Soil organic carbon (SOC) or the carbon found in soil’s organic matter is an important component in the Earth’s carbon cycle and can help mitigate the negative consequences of climate change. Because of its broad relevance to climate and agriculture, the Intergovernmental Panel on Climate Change recommended that the spatial distribution of SOC be carefully monitored. Due to time and cost constraints, spatially-referenced measurements of SOC or “stocks”, e.g. the amount of SOC in a volume, are available only at limited locations. In this talk I will present two Bayesian non-stationary statistical models for SOC with the goal of understanding spatial variability and dependence in SOC for sampling and spatial prediction of SOC. Both approaches model SOC by assuming that the process is globally non-stationary but locally stationary with regions of stationarity identified using different strategies. In one approach, the regions are defined as partitions of the spatial domain where spatially-varying covariates are more homogeneous; in the other, the regions are defined as subsets of the spatial domain with varying strength of spatial dependence.
I will show that inference and SOC predictions yielded by our models are valuable for sampling design and to decision makers, in that they can be used to better benchmark mechanistic models and identify targets for soil restoration projects.

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.)

Subject: GSSI Math Colloquium by Daniel Ueltschi / May 4th at 14.00
To: Alessia Nota <alessia.nota(a)univaq.it>
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).
