Integers in number systems with positive and negative quadratic Pisot base

Preprint English OPEN
Masáková, Zuzana; Vávra, Tomáš;

We consider numeration systems with base $\beta$ and $-\beta$, for quadratic Pisot numbers $\beta$ and focus on comparing the combinatorial structure of the sets $\Z_\beta$ and $\Z_{-\beta}$ of numbers with integer expansion in base $\beta$, resp. $-\beta$. Our main res... View more
