Abstract

The traversal of a self crossing closed plane curve, with points of multiplicity at most two, defines a double occurrence sequence, the Gauss code of the curve. Using the D-switch operation, we give a new simple characterization of these sequences and deduce a simple self-contained proof of Rosenstiehl's characterization.
