Markoff mod-p Graphs: Connectivity, Maximal Divisors, and Generalizations
Matthew Litman
Markoff triples were introduced in 1879 and have a rich history spanning many branches of mathematics. In 2016, Bourgain, Gamburd, and Sarnak answered a long [...]

13/05/2025
11h00 - 12h00
The Oldenburger-Kolakoski sequence is the only infinite sequence over the alphabet {1,2} starting with a "1" and equal to its own derivative. M.S. Keane conjectured [...]

Cops, robbers, infinite graphs and related problems
Gena Hahn
We briefly survey the game of cops-and-robbers on graphs and its variants in the finite case and then concentrate on infinite graphs, stressing the difference [...]

On a group-theoretic generalization of the Morse-Hedlund theorem
Svetlana Puzynina
In their 1938 seminal paper on symbolic dynamics, Morse and Hedlund proved that every aperiodic infinite word x contains at least n+1 distinct factors of [...]

Multiple tilings associated to the symmetric β-expansions
Tomáš Hejda
It is a well-known fact that when β is a d-Bonacci number, the Rauzy fractals arising from the greedy (Rényi) β-transformation tile the contracting hyperplane. [...]

How sticky is the chaos/order boundary?
Carl P. Dettmann
Hamiltonian dynamical systems with mixed phase space are ubiquitous, but notoriously poorly understood, partly due to complicated structure of the boundary between chaotic and ordered [...]

Problème de Waring, et entiers sans grands facteurs premiers
Sary Drappeau
Le problème de Waring est la question de savoir, étant donné k ≥ 1, si tout entier N suffisamment grand peut s'écrire comme somme d'un [...]

Some relations between some stability notions
Dmitry Todorov
There is a strong and long-lasting interest in chaotic dynamical systems as mathematical models of various processes in different areas of science. Like for any [...]
