The pretzel knot $P (4, - 3, 5)$ is not squeezed

Nobuo Iida, Tatsumasa Suzuki

We prove that an infinite family of three-strand pretzel knots is not squeezed. In particular, we show that $P (4, - 3, 5)$ is not squeezed. This answers a question posed by Lewark (…

The non-simply connected Price twist for the 4-sphere

Tsukasa Isoshima, Tatsumasa Suzuki

A cutting and pasting operation on a $P^{2}$ -knot $S$ in a $4$ -manifold is called the Price twist. The Price twist for the $4$ -sphere $S^{4}$ yields at most three $4$ -manifolds up to d…

On the Ozsváth-Szabó $d$ -invariants for almost simple linear graphs

Tatsumasa Suzuki

Karakurt and Şavk computed the Ozsváth-Szabó $d$ -invariants of Brieskorn homology $3$ -spheres arising as surgeries on almost simple linear graphs. In this paper, we refine their fo…
