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 [...]

Fixing monotone boolean networks asynchronously

Adrien Richard

13/03/2018    
11h00 - 12h00
A monotone boolean network with n components is a directed graph on [n]≔{1,…,n} where each vertex is labeled by a binary variable and a local [...]
Systèmes sturmiens de numération et palindromes

Systèmes sturmiens de numération et palindromes

Anna Frid

06/03/2018    
11h00 - 12h00
Je généralise les systèmes de numération d'Ostrowski pour décrire les occurrences des palindromes à un mot sturmien caractéristique et démontrer une conjecture sur les décompositions [...]
Maximum of the Riemann ζ function in typical intervals

Maximum of the Riemann ζ function in typical intervals

Maksym Radziwill

20/02/2018    
11h05 - 12h05
An outstanding problem in analytic number theory is to understand the maximum of the Riemann ζ function on the critical line. The problem is poorly [...]
Constructing space-filling curves of self-similar sets

Constructing space-filling curves of self-similar sets

Hui Rao

13/02/2018    
11h00 - 12h00
We give a general method to construct space-filling curves of self-similar sets. First, we introduce a notion of skeleton of self-similar sets. As soon as [...]
On the topological entropy of the subshifts of finite type on free semigroups

On the topological entropy of the subshifts of finite type on free semigroups

Jung-Chao Ban

06/02/2018    
11h00 - 12h00
In this talk, we provide an effective method to compute the topological entropies of G-subshifts of finite type (G-SFTs) with G = Fd or Sd, [...]
Nilpotent endomorphisms of expansive group actions

Nilpotent endomorphisms of expansive group actions

Ilkka Törmä

30/01/2018    
11h00 - 12h00
Consider a cellular automaton with a special quiescent state 0. The automaton is called nilpotent if it sends every initial configuration to the 0-uniform configuration [...]
