Order symmetry and orthogonality of trajectories in discrete interval exchange transformations
Sébastien S. Ferenczi, Luca Q. Zamboni
Let be a pair of distinct orders on a -letter alphabet The periodic trajectories of a discrete -interval exchange transformations with p…
On Christoffel words & their lexicographic array
Luca Q. Zamboni
By a Christoffel matrix we mean a matrix corresponding to the lexicographic array of a Christoffel word of length In this note we show that if is an integral d…
Clustering and Arnoux-Rauzy words
Sébastien Ferenczi, Luca Q. Zamboni
We characterize the clustering of a word under the Burrows-Wheeler transform in terms of the resolution of a bounded number of bispecial factors belonging to the language generated…
Languages of general interval exchange transformations
Sébastien Ferenczi, Pascal Hubert, Luca Q. Zamboni
The languages generated by interval exchange transformations have been characterized by Ferenczi-Zamboni (2008) and Belov-Cernyatev (2010) under some extra conditions on the system…
On the extremal values of the cyclic continuants of Motzkin and Straus
Alessandro De Luca, Luca Q. Zamboni
In a 1983 paper, G. Ramharter asks what are the extremal arrangements for the cyclic analogues of the regular and semi-regular continuants first introduced by T.S. Motzkin and E.G.…
Continuants with equal values, a combinatorial approach
Gerhard Ramharter, Luca Q. Zamboni
A regular continuant is the denominator of a terminating regular continued fraction, interpreted as a function of the partial quotients. We regard as a function defined on…
