Discrete Tomography: Reconstruction under periodicity constraints
Alberto Del Lungo, Andrea Frosini, Maurice Nivat +1
This paper studies the problem of reconstructing binary matrices that are only accessible through few evaluations of their discrete X-rays. Such question is prominently motivated b…
Characterisation of lattices induced by (extended) Chip Firing Games
Clemence Magnien, Ha Duong Phan, Laurent Vuillon
The Chip Firing Game (CFG) is a discrete dynamical model used in physics, computer science and economics. It is known that the set of configurations reachable from an initial confi…
Coding rotations on intervals
Jean Berstel, Laurent Vuillon
We show that the coding of rotation by on intervals with rationally independent lengths can be recoded over Sturmian words of angle More precisely, for a given …
On the number of return words in infinite words with complexity 2n+1
Laurent Vuillon
In this article, we count the number of return words in some infinite words with complexity 2n+1. We also consider some infinite words given by codings of rotation and interval exc…
