Abstract

It is known that Θ(logn)\Theta(\log n) chords must be added to an nn-cycle to produce a pancyclic graph; for vertex pancyclicity, where every vertex belongs to a cycle of every length, Θ(n)\Theta(n) chords are required. A possibly `intermediate' variation is the following: given kk, 1kn1\leq k\leq n, how many chords must be added to ensure that there exist cycles of every length each of which passes exactly kk chords? For fixed kk, we establish a lower bound of Ω(n1/k)\Omega\big(n^{1/k}\big) on the growth rate.
