Lune-Free Knot Graphs
نویسندگان
چکیده
and Dedication This paper is an exploration of simple four-regular graphs in the plane (i.e. loopless and with no more than one edge between any two nodes). Such graphs are fundamental to the theory of knots and links in three dimensional space, and their planar diagrams. We dedicate this paper to Frank Harary (1921 – 2005) whose fascination with graphs of knots inspired this work and with whom we had the pleasure of developing this paper.

Effect of organic amendment on organic metabolites in root knot nematode (Meloidogyne Incognita) infested spinach
The Nematodes are roundworms that are found in every environment of the earth. While some species are harmful parasites, others play a vital role in nutrient cycle and medical research. Nematode infestation in the fields is poly-specific; however, depending on the agro-climatic conditions, one or two species are dominant over the rest. The present studies attempts to observe and control the roo...

A b-skeleton is a proximity graphs with node neighbourhood defined by continuous-valued parameter b. Two nodes in a b-skeleton are connected by an edge if their lune-based neighbourhood contains no other nodes. With increase of b some edges a skeleton are disappear. We study how a number of edges in b-skeleton depends on b. We speculate how this dependence can be used to discriminate between ra...

A β-skeleton is a proximity graphs with node neighbourhood defined by continuousvalued parameter β.
