Published Papers

Certain codes related to generalized paperfolding sequences.
Yuichi Kamiya
Journal de Theorie des Nombres de Bordeaux   27(1) 149-169   Apr 2015   [Refereed]
We propose a new numeration code C_{b}, and study some properties of the code C_{b}. Among them, We can prove that the difference function of the sum of digits function S_{C_{b}} for C_{b}, {S_{C_{b}}(n)−S_{C_{b}}(n−1)}_{n=1}^{n=∞}, coincides with...
