Forbidden subgraphs for chorded pancyclicity. (English) Zbl 1370.05109
Summary: We call a graph $$G$$ pancyclic if it contains at least one cycle of every possible length $$m$$, for $$3 \leq m \leq | V(G) |$$. In this paper, we define a new property called chorded pancyclicity. We explore forbidden subgraphs in claw-free graphs sufficient to imply that the graph contains at least one chorded cycle of every possible length $$4, 5, \ldots, | V(G) |$$. In particular, certain paths and triangles with pendant paths are forbidden.
