WebWe consider the class of curves of finite total curvature, as introduced by Milnor. This is a natural class for variational problems and geometric knot theory, and since it includes both smooth and polygonal curves, its study shows us connections between discrete and differential geometry. To explore these ideas, we consider theorems of Fáry ... Webcian Karol Borsuk in 1949. The theorem of Milnor combines Fenchel-Borsuk and knot theory, and states that for a non-trivial knot, the total curvature exceeds 4p, i.e. at least two rotations. The theorem was proven indepently, but almost simultanously, by the hun-garian mathematician István Fáry. This is the reason for the name Fáry-Milnor´s ...
