Authors:Jacob D Baron  Jeff Kahn
Abstract:Write urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0001 for the cycle space of a graph G, urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0002 for the subspace of urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0003 spanned by the copies of the κ‐cycle urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0004 in G, urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0005 for the class of graphs satisfying urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0006, and urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0007 for the class of graphs each of whose edges lies in a urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0008. We prove that for every odd urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0009 and urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0010, urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0011 so the urn:x-wiley:10429832:media:rsa20785:rsa20785-math-0012 's of a random graph span its cycle space as soon as they cover its edges. For κ = 3 this was shown in 6].
