Pythagorean triples. II. Growing caterpillar graphs generating Pythagorean triples
en
Hosoya, haruo
Various triplet series of caterpillar graphs are discovered whose topological indices (Z's) represent certain series of mostly primitive Pythagorean triples (PT's). Then quite a new type of method for generating PT's is proposed as follows: Namely one can draw triplet series of caterpillar graphs with mirror symmetry according to the specified recipe, whose Z indices correspond to the edges of a series of PT's. The proof and examples of this theorem are given.
