Long cycles have the edge-Erd\H{o}s-P\'osa property

Combinatorics 2017-05-31 v3

Abstract

We prove that the set of long cycles has the edge-Erd\H{o}s-P\'osa property: for every fixed integer 3\ell\ge 3 and every kNk\in\mathbb{N}, every graph GG either contains kk edge-disjoint cycles of length at least \ell (long cycles) or an edge set XX of size O(k2logk+k)O(k^2\log k + \ell k) such that GXG-X does not contain any long cycle. This answers a question of Birmel\'e, Bondy, and Reed (Combinatorica 27 (2007), 135--145).
