An application of non-positively curved cubings of alternating links

Makoto Sakuma, Yoshiyuki Yokota

By using non-positively curved cubings of prime alternating link exteriors, we prove that certain ideal triangulations of their complements, derived from reduced alternating diagra…

A family of two generator non-Hopfian groups

Donghi Lee, Makoto Sakuma

We construct $2$ -generator non-Hopfian groups $G_{m}, m = 3, 4, 5, \dots$ , where each $G_{m}$ has a specific presentation $G_m=\langle a, b \, | \, u_{r_{m,0}}=u_{r_{m,1}}=u_{r_{m,2}}= \…

The action of the mapping class group on the space of geodesic rays of a punctured hyperbolic surface

Brian H. Bowditch, Makoto Sakuma

Let $Σ$ be a complete finite-area orientable hyperbolic surface with one cusp, and let $R$ be the space of complete geodesic rays in $Σ$ emanating from the puncture. Then…
