Preparing the Internal Approximations of Simple Closed Curves


Andrzej Trybulec
University of Bialystok

Summary.

We mean by an internal approximation of a simple closed curve a special polygon disjoint with it but sufficiently close to it, i.e. such that it is clock-wise oriented and its right cells meet the curve. We prove lemmas used in the next article to construct a sequence of internal approximations.
