ARC NUMBERS FROM GAUSS DIAGRAMS
We characterize planar diagrams which may be divided into n arc embeddings in terms of their chord diagrams, generalizing a result of Taniyama for the case n = 2. Two algorithms are provided, oneExpand

Edge number of knots and links
We introduce a new numerical invariant of knots and links made from the partitioned diagrams. It measures the complexity of knots and links. 1. Why does not a knot come loose?
Complementary Regions of Knot and Link Diagrams
An increasing sequence of integers is said to be universal for knots and links if every knot and link has a reduced projection on the sphere such that the number of edges of each complementary faceExpand
