Purely periodic β-expansions in cubic Salem base in Fq ((x− 1))

F Mahjoub - Publications de l'Institut Mathematique, 2016 - doiserbia.nb.rs
Let Fq be the finite field with q elements and β Salem series in Fq ((X− 1)). It is proved in [15]
that, in this case, all elements in Fq (X, β) have purely periodic β-expansion. We characterize …

ON THE PERIOD OF β-EXPANSION OF PISOT OR SALEM SERIES OVER Fq ((x− 1))

G Rim, Z Sourour - 대한수학회보, 2015 - dbpia.co.kr
In [6], it is proved that the lengths of periods occurring in the β-expansion of a rational series
r noted by Perβ (r) depend only on the denominator of the reduced form of r for quadratic …
