Let $T(2,3)$ be the trefoil knot, and consider folded ribbon realizations whose ribbon is a topological Möbius band. Let ${\operatorname{Rib}}$ denote folded ribbonlength and take…

For the trefoil knot $K$, let $\bar\tI^{N}_{*}(K)$ denote its reduced instanton homology groups. The critical set of the unperturbed functional has two components: a copy of…
