Let $K$ be a knot with non-trivial classical Arf invariant, and let its Bing double be the associated 2-component link. Framed Bing-double conjecture. The Bing double of any such k…

Let $K$ be a knot, and let $B(K)$ denote its Bing double. A link is smoothly slice when it bounds disjoint smoothly embedded disks in the relevant four-dimensional setting. Bing-do…
