Finite presentations of the mapping class groups of once-stabilized Heegaard splittings

Daiki Iguchi

Let $g \geq 2$ and assume that we are given a genus $g$ Heegaard splitting of a closed orientable $3$ -manifold with the distance greater than $2 g + 2$ . We prove that the mapping class…

Thick isotopy property and the mapping class groups of Heegaard splittings

Daiki Iguchi

We give a necessary and sufficient condition for the fundamental group of the space of Heegaard splittings of an irreducible $3$ -manifold to be finitely generated. The condition is…
