Ribbon concordance and fibered predecessors
John A. Baldwin, Steven Sivek
Given any knot K in the 3-sphere, we prove that there are only finitely many hyperbolic fibered knots which are ribbon concordant to K. It follows that every fibered knot in the 3-…

Homology lens spaces and
Sudipta Ghosh, Steven Sivek, Raphael Zentner
We prove that if is a closed, oriented 3-manifold with first homology of order less than , then there is an irreducible representation $π_1(Y) \to \mathr…

Pseudo-Anosov flows on hyperbolic L-spaces
John A. Baldwin, Steven Sivek, Jonathan Zung
We prove that for each there is a hyperbolic L-space with pseudo-Anosov flows, no two of which are orbit equivalent. These flows have no perfect fits and are t…
