As an exception, this last week's seminar won't consist in a scientific presentation, but will instead be devoted to a social event. Please bring drinks, [...]
A linear monadic second-order logic over omega-words

A linear monadic second-order logic over omega-words

Colin Riba

(j.w.w. P. Pradic) We present LMSO, a linear logic-based variant of MSO over omega-words. LMSO can be seen as a logical syntax for a Curry-Howard-Lambek-like [...]

Walking On A Line: finding S-adic walks in an ω-automaton

Walking On A Line: finding S-adic walks in an ω-automaton

Pierre Béaur

At the heart of symbolic dynamics lies the study of languages, infinite words and the dynamical structures associated. We focus on two classical methods to [...]
Incompressible limit and rate of convergence for tumor growth models with drift

Incompressible limit and rate of convergence for tumor growth models with drift

Noemi David

Both compressible and incompressible porous medium models have been used in the literature to describe the mechanical aspects of living tissues. Using a stiff pressure [...]
Polytope Extensions with Small Diameter

Polytope Extensions with Small Diameter

Kirill Kukharenko

Bounding the combinatorial diameter of a polytope is a well-known and long-standing open problem. The great theoretical and practical interest in this question originates from [...]
Zonoid calculus: How to multiply convex bodies to count points of intersection

Zonoid calculus: How to multiply convex bodies to count points of intersection

Léo Mathis

09/12/2022    
11h00 - 12h00
The space of convex bodies (convex non empty and compact subsets) comes with an addition called the Minkowski sum. I will explain how on a [...]

Des histoires de catégories (2, où un réel est positif quand il est plus grand que tous les réels négatifs)

Rémy Cerda

Category theory is a mathematical framework developped since the 1940s to provide a general description of “relations between objects”, which has been fruitfully used since [...]
Efficient resolution of Thue-Mahler equations (reporté)

Efficient resolution of Thue-Mahler equations (reporté)

Adela Gherga

Let F be a homogenous irreducible form of degree at least 3 with integer coefficients. A Thue-Mahler equation is a Diophantine equation of the form [...]
Comptage des géodésiques fermées sous contraintes d'intersection

Comptage des géodésiques fermées sous contraintes d'intersection

Yann Chaubet

Sur une surface fermée à courbure négative, Margulis a explicité la croissance asymptotique du nombre de géodésiques fermées de longueurs bornées, quand la borne tend [...]
Comptage de représentations cuspidales automorphes à ramifications de niveau zero

Comptage de représentations cuspidales automorphes à ramifications de niveau zero

Hongjie Yu

En 1981, Drinfeld a compté le nombre de systèmes locaux l-adiques irréductibles de rang deux sur une courbe sur un corps fini. Deligne propose des [...]

Les groupes auto-similaires contractants

Les groupes auto-similaires contractants

Nikolai Prochorov

La théorie de groupes auto-similaires relie d'une belle manière différents domaines de mathématiques, par exemple, topologie, combinatoire, systèmes dynamiques et la théorie géométrique des groupes. [...]
Homomorphisms between multidimensional substitutive subshifts

Homomorphisms between multidimensional substitutive subshifts

Christopher Cabezas

02/12/2022    
11h00 - 12h00
Homomorphisms are topological factors between topological dynamical systems, up to GL(d,Z)-transformations, so they represent further symmetries in a topological dynamical system, such as rotations and reflections. [...]
Electrons in two dimensions

Electrons in two dimensions

Kishore Iyer

The effect of inter-particle interactions become more important as we go to lower dimensions. In this talk, we will look at interesting behaviour of electrons [...]
A proof of the Erdős primitive set conjecture

A proof of the Erdős primitive set conjecture

Jared D. Lichtman

A set of integers greater than 1 is primitive if no member in the set divides another. Erdős proved in 1935 that the sum of [...]
