On the topological structure of the space of ℤᵈ-subshifts
Alonso Herrera Nuñez (LIX)
10/02/2026
11h00 - 12h00
The space 𝓢ᵈ of ℤᵈ-subshifts, d≥1, endowed with the Hausdorff topology, provides a natural framework for the study of generic properties, as it admits an [...]
Événements passés
Cops, robbers, infinite graphs and related problems
Gena Hahn (Université de Montréal, Canada)
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 (Sobolev Institute of Mathematics, Novosibirsk, Russia)
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 (CTU in Prague)
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 (University of Bristol, UK)
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 (I2M, Aix-Marseille Université)
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 (Centre de Recerca Matematica in Barcelona)
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 [...]
