Optical characterization of nanocrystallized AlN:Er films prepared by magnetron sputtering
Valerie Brien, Manuel Dossot, Hervé Rinnert +3
In the prospect of understanding the photoluminescence mechanisms of AlN films doped with erbium and targeting photonic applications we have synthesized non doped and Er-doped AlN…
On a conjecture of Helleseth
Yves Aubry, Philippe Langevin
We are concern about a conjecture proposed in the middle of the seventies by Hellesseth in the framework of maximal sequences and theirs cross-correlations. The conjecture claims t…
Vectorial solutions to list multicoloring problems on graphs
Yves Aubry, Jean-Christophe Godin, Olivier Togni
For a graph with a given list assignment on the vertices, we give an algebraical description of the set of all weights such that is -colorable, called permis…
Dual billiards, Fagnano orbits and regular polygons
Serge Troubetzkoy
We study the notion of Fagnano orbits for dual polygonal billiards. We used them to characterize regular polygons and we study the iteration of the developing map.
Periodic billiard orbits in right triangles II
Serge Troubetzkoy
Periodic billiard orbits are dense in the phase space of an irrational right triangle. A stronger pointwise density result is also proven.
Always Finite Entropy and Lyapunov exponents of two-dimensional cellular automata
Pierre Tisseur
Given a new definition for the entropy of a cellular automata acting on a two-dimensional space, we propose an inequality between the entropy of the shift on a two-dimensional latt…
