Let $K$ be a knot, and let $D_1$ and $D_2$ be slice disks for $K$ in $B^4$. Their positive Whitehead doubles are the slice disks obtained by applying the positive Whitehead satelli…

Let $K$ be a knot in $\mathbb{S}^3$. The deform-spun slice disks $D_{K,r}$ and $D_{K,t}$ lie in \operatorname{Surf}_0(-K\\#K), and $\mu_{st}$ denotes their stabilization distance…
