Periodic Infinite Frieze Patterns of Type ${\Lambda }_{p_1,\dots ,p_n}$ and Dissections on Annuli

Esther Banaian, Jiuqi Chen

Finite frieze patterns with entries in $\mathbb{Z}[{\lambda }_{p_1},\dots ,{\lambda }_{p_s}]$ where $\{p_1,\dots ,p_s\}\subseteq {\mathbb{Z}}_{\ge 3}$ and ${\lambda }_p=2\cos (\pi /p)$ were shown to have a co…
