Let a collectionof generically immersed curves be given in an oriented surface. To each component circle, associate a Gauss word by traveling once around the circle and recording the crossing points with signs. The set of these words forms a Gauss paragraph. Ifandfill the surfacein the sense that the complementary regions are disks, then there is a homeomorphism oftaking one to the other if and only ifandhave isomorphic Gauss paragraphs. This notion of isomorphism is defined here; it ignores the choices made in defining the Gauss words. References
