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 [...]

Frequences in self-descriptive sequences

Mai-Linh Tran-Cong

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 [...]

14h30 - 15h30
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 [...]

11h00 - 12h00
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

24/11/2015    
11h00 - 12h00
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?

How sticky is the chaos/order boundary?

Carl P. Dettmann

17/11/2015    
11h05 - 12h00
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

10/11/2015    
11h05 - 12h05
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

Some relations between some stability notions

Dmitry Todorov

03/11/2015    
11h00 - 12h00
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 [...]
