Topology Appl.   to appear (掲載決定)    2019   [Refereed]
Let K be a nontrivial knot in the 3-sphere with the exterior E(K), and denote the fundamental group of E(K) by G(K). We prove that for any hyperbolic knot K and any nontrivial element g in G(K), there are only finitely many Dehn fillings of E(K) w...

Kenneth L. Baker and Kimihiko Motegi
Comm. Anal. Geom.   to appear (掲載決定)    2019   [Refereed]
Conjecturally, there are only finitely many Heegaard Floer L-space knots in the 3-sphere of a given genus. We examine this conjecture for twist families of knots {K_n} obtained by twisting a knot K along an unknot c in terms of the linking number...
