Center node: "point separable classes of simple computable planar curves"
  Abstract: In mathematics curves are typically defined as the images of continuous real#N#functions (parametrizations) defined on a closed interval. They can also be#N#defined as connected one-dimensional compact subsets of points. For simple#N#curves of finite lengths, parametrizations can be further required to be#N#injective or even length-normalized. All of these four approaches to curves are#N#classically equivalent. In this paper we investigate four different versions of#N#computable curves based on these four approaches. It turns out that they are#N#all different, and hence, we get four different classes of computable curves.#N#More interestingly, these four classes are even point-separable in the sense#N#that the sets of points covered by computable curves of different versions are#N#also different. However, if we consider only computable curves of computable#N#lengths, then all four versions of computable curves become equivalent. This#N#shows that the definition of computable curves is robust, at least for those of#N#computable lengths. In addition, we show that the class of computable curves of#N#computable lengths is point-separable from the other four classes of computable#N#curves.
