Dear Colleagues,
We would like to invite you to the following SPASS seminar, jointly
organized by UniPi, SNS, UniFi and UniSi (abstract below):
*Hölder continuous solutions to inhomogeneous incompressible Euler flows*
by *Ujjwal Koley* (Center for Applicable Mathematics, Tata Institute of
Fundamental Research, Bangalore)
The seminar will take place on *TUE, 01.07.2025* at *11:00 CEST *(mind
unusual time) in Aula M-Lab, Polo Fibonacci, UNIPI and streamed online at this
link <https://meet.google.com/gji-phwo-vbg>.

*Title: **Hölder continuous solutions to inhomogeneous incompressible Euler
flows*
*Abstract: In this talk, we shall *discuss about the* construction of
global-in-time Hölder continuous weak solutions to density dependent
incompressible Euler equations in three-dimensional periodic domain. The
proof is based on convex integration techniques using Mikado flows as
building blocks. As a main novelty with respect to the related literature,
our result produces Hölder continuous density.*
Dear colleagues,
I would like to advertise the call for PhD scholarships in Mathematics and
PhD scholarships in High Performance Scientific Computing at University of
Pisa.
Deadline: July 18, 2025, 1pm Rome time zone.
We strongly encourage applications of students interested in probability.
The research interests of our probability group here in Pisa include:
stochastic evolutions (e.g. stochastic partial differential equations,
regularization by noise, stochastic fluid dynamics), probabilistic methods
in machine learning (e.g. learning dynamics for neural networks),
variational problems in commutative and non-commutative setting (e.g.
quantum probability, random optimal transport, Malliavin calculus),
interacting particle systems (e.g. propagation of chaos, large deviations).
See also our webpage:
https://www.dm.unipi.it/research/probability-and-mathematical-statistics/
Our group carries out (together with Scuola Normale, Firenze and Siena) the
"probability, stochastic analysis and statistics seminar series". PhD
students can also enjoy study groups and informal seminars which usually
run at University of Pisa or at Scuola Normale Superiore in Pisa.
The Department of Mathematics has been awarded with the excellence
framework (Dipartimento di eccellenza) for the period 2023-2027. More
information on the PhD programs in Mathematics and in High Performance
Scientific Computing are available here:

Dear colleagues,
(With apologies for cross-posting)
On 26 June 2025 at 2pm (CET)
Marta Leocata (LUISS Guido Carli, Department of AI, Data and Decision
Sciences)
will present an online seminar whose title is:
Two applications of multi-agent models in economic and social systems
Abstract: In this talk, we present an overview of mathematical models that
capture the behavior of myopic agents—who rely on short-term, local
information in their decision-making—and strategic agents, who consider the
long-term consequences of their actions within interactive environments.
These concepts will be illustrated through two applications in economic and
social contexts: a multi-agent model for the co-evolution of preferences
and actions in the emergence of social norms (joint work with Michele
Aleandri, LUISS, and Laura Marcon, CNR), and a Mean Field Game approach to
the Emission Trading System (joint work with Giulia Livieri, LSE, and
Gianmarco Del Sarto, TU Darmstadt).
The seminar link is: https://uniroma1.zoom.us/j/87022289921
This is the first seminar of a series of three seminars organised by
UMI-PRISMA on the Applications of Probability to Economics in preparation
to the 2025 Summer School of Mathematics for Economic and Social Sciences:
https://indico.sns.it/event/105/overview

Life Insurance Applications
on 17 July 2025, Sara Merino Aceituno (Faculty of Mathematics, University

Dear all,
can I kindly ask you to diffuse the following announcement?
- July 15 11.00, aula Levi-Civita Dipartimento di Matematica Guido
Castelnuovo Sapienza University Roma Piazzale Aldo Moro, 5 – Roma,
*Pierre-Louis Lions*
*Collège de France, Paris*
*Mathematics and the Real World Today… and Tomorrow?* *On mathematics and
their applications.*
*Abstract*: It is well-known that mathematics are everywhere nowadays, from
the design and improvement of most things that we use every day to the
ubiquitous algorithms that govern our lives more and more. After a brief
discussion of the nature of maths today, we wish to recall some historical
facts that go back to the dawn of mathematics and that emphasize the fast
growing role of mathematics with the use of computers and machine learning
(AI). We shall describe how real world problems are being tacked with the
help of mathematical models and equations that are often partial
differential equations. And we wish to emphasize how the study of
applications goes hand in hand with the development of maths. We will do so
by discussing, without mathematical details, examples using Mean Field
Games theory or random matrices.
Best regards,
Thierry Paul.

Dario Trevisan, Dipartimento di Matematica , Università di Pisa , terrà il seminario:
Convergenza quantitativa delle reti neurali profonde ai processi gaussiani
Astratto
In questo seminario, esploriamo la convergenza quantitativa di ampie reti neurali profonde con pesi gaussiani a processi gaussiani, stabilendo nuove velocità per la loro approssimazione gaussiana. Mostriamo che la distanza di Wasserstein tra l'output della rete e la sua controparte gaussiana scala inversamente alla larghezza della rete, con limiti applicabili a qualsiasi insieme finito di input in specifiche condizioni di non degenerazione delle covarianze. Inoltre, estendiamo la nostra analisi al framework bayesiano, studiando i posteriori esatti per le reti neurali, quando dotate di priori gaussiani e funzioni di verosimiglianza regolari, ma forniamo anche recenti progressi nell'approssimazione quantitativa di reti addestrate tramite discesa del gradiente nel regime NTK.
Basato su lavori congiunti con A. Basteri, A. Agazzi ed E. Mosig.
Il seminario si svolgerà presso la sede CNR-IAC di Roma , sala al primo piano , in modalità mista: in presenza e in streaming al link https://www.youtube.com/watch?v=RMKVBN5l13g

Title: Spectral Statistics of Large Random Matrices
Abstract:
The last fifteen years have brought major breakthroughs in understanding the spectra of large random matrices. I'll discuss several recent advances in eigenvalue and eigenvector statistics for both Hermitian and non-Hermitian matrices, focusing on the universal patterns that emerge.

Title: Logarithmically Correlated Fields from Random Matrices.
Abstract:
In 2012, Fyodorov, Hiary, and Keating discovered a new connection between random matrices and extremal values of logarithmically correlated fields, such as branching Brownian motion and the 2D Gaussian Free Field.
In particular, they conjectured that extreme statistics of random characteristic polynomials of unitary matrices belong to the universality class of logarithmically correlated fields, which was first identified by Bramson in his seminal work on branching Brownian motion.
I will review several contributions in proving this connection and present some new recent works establishing new connections of characteristic polynomials of non-Hermitian matrices and two- and three-dimensional logarithmically correlated fields.
