A note on smoothly slice links in $S^{2} \times S^{2}$

Marco Marengon, Clayton McDonald

We give an alternative proof of a result of Miyazaki and Yasuhara that there exists links that are not smoothly slice in $S^{2} \times S^{2}$ . We discuss potential applications to the…

Splitting links by integer homology spheres

Marco Golla, Marco Marengon

For every $n \geq 3$ , we construct 2-component links in $S^{n + 1}$ that are a split by an integer homology $n$ -sphere, but not by $S^{n}$ . In the special case $n = 3$ , i.e. that of 2-lin…

Smoothly slice links in $CP^{2} # CP^{2}$

Marco Marengon, Clayton McDonald

We show that there exists a link with 2 components which is not smoothly slice in $CP^{2} # CP^{2}$ . By contrast, it is well-known that every knot (i.e.,…
