Properties of minimal charts and their applications VII: charts of type $(2, 3, 2)$

Teruo Nagase, Akiko Shima

Let $Γ$ be a chart, and we denote by $Γ_{m}$ the union of all the edges of label $m$ . A chart $Γ$ is of type $(2, 3, 2)$ if there exists a label $m$ such that $w (Γ) = 7$ , $w(Γ_m\capΓ_{m+…
