Popis: | The Kneser graph K(n, k) has as its vertex set all k-subsets of an n-set and two k-subsets are adjacent if they are disjoint. The odd graph Ok is a special case of Kneser graph when n = 2k + 1. A long standing conjecture claims that Ok is hamiltonian for all k>2. We show that the prism over Ok is hamiltonian for all k even. © 2010 Wiley Periodicals, Inc. J Graph Theory 68:177-188, 2011 © 2011 Wiley Periodicals, Inc. |
