Automorphisms of the Torelli complex for the one-holed genus two surface
Yoshikata Kida, Saeko Yamagata
Let S be a connected, compact and orientable surface of genus two having exactly one boundary component. We study automorphisms of the Torelli complex for S, and describe any isomo…
Examples of amalgamated free products and coupling rigidity
Yoshikata Kida
We present amalgamated free products satisfying coupling rigidity with respect to the automorphism group of the associated Bass-Serre tree. As an application, we obtain orbit equiv…
The co-Hopfian property of surface braid groups
Yoshikata Kida, Saeko Yamagata
Let g and n be integers at least two, and let G be the pure braid group with n strands on a closed orientable surface of genus g. We describe any injective homomorphism from a fini…
Commensurators of surface braid groups
Yoshikata Kida, Saeko Yamagata
We prove that if g and n are integers at least two, then the abstract commensurator of the braid group with n strands on a closed orientable surface of genus g is naturally isomorp…
