Thematic Trimester on “Low-Resource Settings in AI”
14 September
Current advances in Artificial Intelligence (AI) mainly come from the development and training of neural based architectures in machine learning. In particular, Pre-trained Language Models (PLMs) and, among them, Large Language Models (LLMs), Visual Language …
Thematic semester 2026 : Interacting particles, PDEs and applications
3 Mars
Many complex systems in physics, biology, and the social sciences consist of a large number of interacting agents whose emergent behavior can often be described by nonlinear PDEs. Over recent decades, significant progress has been made in understanding the …
"Gaston Darboux, la profondeur des surfaces" : an exhibition presented at the library from 1 Dec. 2025 to 16 Jan. 2026
5 December
From 1 December 2025 to 16 January 2026, the library will host the exhibition ‘Gaston Darboux, la profondeur des surfaces’ (Gaston Darboux, the depth of surfaces), produced by the Institut Henri Poincaré. On Friday 5 December, Frédéric Brechenmacher will give …
VIDEO - You will finally understand quantum mechanics
10 November
The QTraj (Quantum Trajectories) research project led by Tristan Benoist is funded by the ANR. This episode is produced as part of the Science with and for Society project ‘CONNECTS 2’ led by the University of Toulouse (Comue) and funded by the ANR. To find …

Free energy analyticity of the disordered XY and 2D Coulomb gas models.

Séminaire de Probabilités

D'Alimonte, Lucas
29 September 2026, 09:50 → 10:50

In this talk, I will consider three models of statistical mechanics: the classical XY model in arbitrary dimension, the lattice Coulomb gas in dimension two, and the square well model in arbitrary dimension. For …

Quantitative Metastability in the Linear Becker-Döring Equations

Séminaire MAC

Benítez Berral, Inmaculada
29 September 2026, 11:15 → 12:15

The Becker-Döring equations describe the dynamics of cluster formation and have long been known to exhibit metastable behaviour near the critical monomer concentration. In the linear setting, where the monomer …

Rigidité pour le groupe de Cremona

Séminaire de Géométrie et Topologie

Lamy, Stéphane
29 September 2026, 11:15 → 12:15

Le théorème de rigidité d'Ivanov stipule que tout automorphisme du complexe des courbes est induit par un élément du mapping class group. Dans cet exposé, j'expliquerai un résultat analogue pour le groupe de …

Quid of Braid Groups and Homological Representations

Séminaire QUID

Brevidelli, Thiago
30 September 2026, 18:00 → 19:30
1R2-207

Given a group G, it is natural to ask whether or not it is linear, i.e., if G is isomorphic to a subgroup of GLN(R) for some N and some ring R. In this seminar, we will answer this question for the group G = Bn, the …

Formule(s) de dégénérescence

Géométrie Énumérative

1 October 2026, 09:00 → 10:00
IMT

Soit X un objet géométrique (variété complexe, algébrique, symplecique,...). Un problème énumératif consiste à compter les sous-objets satisfaisant des contraintes fixées. Une idée naturelle consiste à dégénérer X, …

Variétés kählériennes compactes à revêtements universels biholomorphes et dimension de Kodaira

Séminaire de Géométrie Complexe

Diverio, Simone
1 October 2026, 10:15 → 11:30

La dimension de Kodaira est un invariant biméromorphe discret fondamental des variétés kählériennes compactes. D'après le théorème d'uniformisation, deux surfaces de Riemann compactes ont la même dimension de …

A solution to 2-copy distillability of Werner states

Séminaire Maths-Physique

Park, Sang-Jun
1 October 2026, 11:00 → 12:00
Bât. 1R3

Entanglement distillation is a fundamental task in quantum information theory. In this work, we prove that Werner states in arbitrary dimension are 2-copy distillable if and only if they are 1-copy distillable and …

Uniqueness, symmetry and nodal sets for a Ginzburg–Landau type problem in an infinite strip

Séminaire d'Analyse

Aftalion, Amandine
1 October 2026, 11:15 → 12:15

The Ginzburg-Landau energy is studied in a specific geometry: an infinite strip with Neumann boundary conditions and under symmetry properties related to very experiments in Bose Einstein condensates. We show that …
