WitrynaShortening embedded curves By MArrHEw A. GRAYSON* 0. Introduction The curve shortening problem is to analyze the long-term behavior of smooth curves, immersed in a Riemannian surface, which evolve by their curvature vectors. Although evolution by curvature is a natural way to shorten curves, it leads to a number of complex problems. WitrynaConjecture 2. Given any immersed curve T in the plane, there is a positive integer m such that for every n ≥ m there is an immersed curve Tn which has the same values of St, J+ and J− as T, and such that Tn has exactly n inscribed squares. Moreover there is k (independent of n) such that all but k many of the inscribed

Witryna6 mar 2024 · Immersed plane curves have a well-defined turning number, which can be defined as the total curvature divided by 2 π. This is invariant under regular homotopy, by the Whitney–Graustein theorem – topologically, it is the degree of the Gauss map, or equivalently the winding number of the unit tangent (which does not vanish) about the …
