Local Knots, $I^½^{+}$ -Sharp Knots, and Rational Slice Genus

Junghwan Park, Zhongtao Wu, Jingling Yang

Hom and Wu introduced the knot concordance invariant $I^½^{+}$ for knots in $S^{3}$ and proved that it gives a lower bound for the slice genus. Wu and Yang extended $I^½^{+}$ to knot…

Distance one surgeries on the lens space $L (n, 1)$

Jingling Yang

In this paper, we show that the lens space $L (s, 1)$ for $s \neq = 0$ is obtained by a distance one surgery along a knot in the lens space $L (n, 1)$ with $n \geq 5$ odd only if $n$ an…

Surgeries between lens spaces of type $L (n, 1)$ and the Heegaard Floer $d$ -invariant

Zhongtao Wu, Jingling Yang

We establish a $d$ -invariant surgery formula for $L$ -space knots that provides an effective tool for studying surgeries between lens spaces. Using this formula, we classify distanc…
