Abstract

A graph is P8P_8-free if it contains no induced subgraph isomorphic to the path P8P_8 on eight vertices. In 1995, Erd\H{o}s and Gy\'{a}rf\'{a}s conjectured that every graph of minimum degree at least three contains a cycle whose length is a power of two. In this paper, we confirm the conjecture for P8P_8-free graphs by showing that there exists a cycle of length four or eight in every P8P_8-free graph with minimum degree at least three.
