On the total curvature of knots

WebWe first study the minimum total curvature of a knot when it is embedded on the cubic lattice. Let K be a knot or link with a lattice embedding of minimum total curvature τ(K) among all possible lattice embeddings of K. We show that there exist positive constants c 1 and c 2 such that c 1 √ Cr(K) τ(K) c 2Cr(K) for any knot type K ... WebThe title of the paper was “On the Total Curvature of Knots”. Could you tell us how you got the idea for that paper? Milnor: I was taking a course in differential geom-etry under Albert Tucker. We learned that Werner Fenchel, and later Karol Borsuk, had proved the following statement: the total curvature of a closed

WebWe present an exposition of various results dealing with the total curvature of curves in Euclidean 3-space. There are two primary results: Fenchel’s theorem and the theorem of Fary and Milnor. Fenchel’s theorem states that the total curvature of a simple closed curve is greater than or equal to 2ˇ, with equality if and only if the 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. how many gs can a fighter pilot pull https://reoclarkcounty.com
