View PDF View article View in Scopus Google Scholar [5] 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. smart drive watch change the time

One can construct knots in which the crossing numbers grow as fast as the (4/3) power of L/R. Our theorem says that such families must have unbounded total curvature: If the total curvature is bounded, then the rate of growth of crossings with ropelength
