Abstract
The Hamiltonian path graph H(G) of a graph G is that graph having the same vertex set as G and in which two vertices u and v are adjacent if and only if G contains a Hamiltonian uโv path. A characterization of Hamiltonian graphs isomorphic to their Hamiltonian path graphs is presented.

The hamiltonian path graph H(F) of a graph F is that graph having the same vertex set as F and in which two vertices u and u are adjacent if and only if F contains a hamiltonian u -u path. First, in response to a conjecture of Chartrand, Kapoor and Nordhaus, a characterization of nonhamiltonian grap
It is shown that, if t is an integer !3 and not equal to 7 or 8, then there is a unique maximal graph having the path P t as a star complement for the eigenvalue ร2: The maximal graph is the line graph of K m,m if t ยผ 2mร1, and of K m,m รพ1 if t ยผ 2m. This result yields a characterization of L(G ) wh
We give a simple proof that the obvious necessary conditions for a graph to contain the k th power of a Hamiltonian path are sufficient for the class of interval graphs. The proof is based on showing that a greedy algorithm tests for the existence of Hamiltonian path powers in interval graphs. We wi
## Abstract This article deals with a study of novel classes of metamaterial inclusions based on spaceโfilling curves. The graphโtheoretic Hamiltonianโpath (HP) concept is exploited to construct a fairly broad class of spaceโfilling curve geometries that include as special cases the wellโknown Hilb
