Global curvature, thickness, and the ideal shapes of knots.

چکیده
The global radius of curvature of a space curve is introduced. This function is related to, but distinct from, the standard local radius of curvature and is connected to various physically appealing properties of a curve. In particular, the global radius of curvature function provides a concise characterization of the thickness of a curve, and of certain ideal shapes of knots as have been investigated within the context of DNA.

Local Structure of Ideal Shapes of Knots
Relatively extremal knots are the relative minima of the ropelength functional in the C1 topology. They are the relative maxima of the thickness (normal injectivity radius) functional on the set of curves of xed length, and they include the ideal knots. We prove that a C1;1 relatively extremal knot in Rn either has constant maximal (generalized) curvature, or its thickness is equal to half of ...
متن کاملLocal Structure of Ideal Shapes of Knots, II Constant Curvature Case
The thickness, NIR(K) of a knot or link K is defined to be the radius of the largest open solid tube one can put around the curve without any self intersections of the normal discs, which is also known as the normal injectivity radius ofK. For C1,1 curvesK, NIR(K) = min{ 1 2 DCSC(K), 1 supκ(K) )}, where κ(K) is the generalized curvature, and the double critical self distance DCSD(K) is the shor...

متن کاملComputation and Visualization of Ideal Knot Shapes THÈSE
We investigate numerical simulations and visualizations of the problem of tying a knot in a piece of rope. The goal is to use the least possible rope of a fixed, prescribed radius to tie a particular knot, e.g. a trefoil, a figure eight, and so on. The ropelength of the knot, the ratio to be minimized, is its length divided by its radius. An overview of existing algorithms to minimize the ropel...
متن کاملSubknots in ideal knots, random knots, and knotted proteins
We introduce disk matrices which encode the knotting of all subchains in circular knot configurations. The disk matrices allow us to dissect circular knots into their subknots, i.e. knot types formed by subchains of the global knot. The identification of subknots is based on the study of linear chains in which a knot type is associated to the chain by means of a spatially robust closure protoco...
