Let an oriented link be a boundary link if its components bound pairwise disjoint Seifert surfaces in $S^3$. Let the trivial link be the link whose components are disjoint unknotte…

Let $q>1$ and let $(L,\varphi)$ be an $F_m$-link concordance class in $C_{2q+1}(F_m)$. For each positive integer $k$, let $R_k(F_m)$ denote the space of $k$-dimensional unitary rep…

Let $L$ range over the $2$-component pretzel links that McCoy and McDonald proved are weakly doubly slice for all orientations but not strongly doubly slice. A link in $S^3$ is a b…
