"Webif a curve γ in R3 has 2−width n, then some planar projection of γ has total curvature at most 2πn3/2. This can be viewed in contrast to the Fary-Milnor Theorem. While small bridge number does not imply that some projection has small total curvature, small 2-thickness does imply this. In Section 2 we introduce k-width for curves in R3.

Milnor shows (using proposition 1.2 in the paper), that you can always decrease the curvature slightly by an isotopy, so the inf is never attained.

WebIn the mathematical field of knot theory, a knot invariant is a quantity (in a broad sense) defined for each knot which is the same for equivalent knots. The equivalence is often given by ambient isotopy but can be given by homeomorphism.
