Palindromic Sequences of the Markov Spectrum
M. van Son University of Liverpool, Liverpool, L69 3BX United Kingdom
Abstract:
We study the periods of Markov sequences, which are derived from the continued
fraction expression of elements in the Markov spectrum.
This spectrum is the set of
minimal values of indefinite binary quadratic forms that are specially normalised.
We show
that the periods of these sequences are palindromic after a number of circular shifts, the
number of shifts being given by Stern's diatomic sequence.
Keywords:
Markov sequence, Stern's diatomic series, Stern's diatomic sequence, palindromic
sequence, evenly palindromic, Christoffel words.
