Let $M$ be a topological $4$-manifold, let ${\vee}^3 S^1$ denote the wedge of three circles, and let ${\mathcal S}^0(Wh(Bor))$ denote the zero-framed surgery on the Whitehead doubl…

Let ${\rm Wh}({\rm Bor})$ denote the untwisted Whitehead double of the Borromean Rings. A link is freely topologically slice if its components bound disjoint locally flat disks in…
