Hamiltonian Sets of Polygonal Paths in Assembly Graphs

Combinatorics 2026-03-10 v1

Abstract

We provide four equivalent combinatorial conditions for a simple assembly graph (rigid vertex graph where all vertices are of degree 1 or 4) to have the largest number of Hamiltonian sets of polygonal paths relative its size. These conditions serve to prove the conjecture that such maximum, which is equal to F2n+11F_{2n+1}-1, where FkF_k denotes the kkth Fibonacci number, is achieved only for special assembly graphs, called tangled cords.
