Labeled Fibonacci Trees
Stéphane Legendre
The study describes a class of integer labelings of the Fibonacci tree, the tree of descent introduced by Fibonacci. In these labelings, Fibonacci sequences appear along ascending…
Trophic groups and modules: two levels of group detection in food webs
Benoit Gauzens, Elisa Thébault, Gérard Lacroix +1
Within food webs, species can be partitioned into groups according to various criteria. Two notions have received particular attention: trophic groups, which have been used for dec…
A General Formula for the Generation Time
François Bienvenu, Lloyd Demetrius, Stéphane Legendre
We show that the generation time -- a notion usually described in a biological context -- can be defined in a general way as a return time in a conveniently constructed finite Mark…
Foldings and Meanders
Stéphane Legendre
We review the stamp folding problem, the number of ways to fold a strip of stamps, and the related problem of enumerating meander configurations. The study of equivalence class…
The Number System of the Permutations Generated by Cyclic Shift
Stéphane Legendre
A number system coding for the permutations generated by cyclic shift is described. The system allows to find the rank of a permutation given how it has been generated, and to dete…
