Generalized torsion and decomposition of 3-manifolds
Tetsuya Ito, Kimihiko Motegi, Masakazu Teragaito
A nontrivial element in a group is a generalized torsion element if some nonempty finite product of its conjugates is the identity. We prove that any generalized torsion element in…

Positivities of knots and links and the defect of Bennequin inequality
Jesse Hamer, Tetsuya Ito, Keiko Kawamuro
We discuss relations among various positivities of knots and links, such as strong quasipositivity and quasipositivity. We give several pieces of supporting evidence for conjectura…

On the fractional Dehn twist coefficients of branched coverings
Tetsuya Ito, Keiko Kawamuro
We discuss how the fractional Dehn twist coefficient behaves under a fully ramified branched covering of an open book, and give applications to both topological and contact 3-manif…
