(1,1) non-L-space knots are persistently foliar

Qingfeng Lyu

We prove that (1,1) non-L-space knots in $S^{3}$ and lens spaces are persistently foliar. This verifies the L-space knot conjecture of Delman-Roberts for (1,1) knots, thus providing…

Torus decomposition and foliation detected slopes

Qingfeng Lyu

Let $M_{1}$ and $M_{2}$ be knot manifolds and $M = M_{1} \cup_{f} M_{2}$ be the closed 3-manifold obtained by gluing up $M_{1}$ and $M_{2}$ via $f : \partial M_{1} ≅ \partial M_{2}$ . We…
