Title: | Complex Pisot Numeration Systems |
Abstract: | We will introduce results by Hama, Furukado and Ito on a generalization of classical $\beta$-numeration to complex bases. That is, on the $\lambda$-expansion of a complex number $z$ in the form $z=\sum_{n=k}^{\infty}a_n\lambda^{-n}$, $a_n\in\Gamma$, where $\Gamma$ is a finite set in $\mathbb{Z}[\lambda]$ and $\lambda$ is a complex Pisot number. |
