Erratum: A Cheeger inequality of a distance regular graph using Green's function (Discrete Mathematics (2013) 313:20 (2337-2347))

초록/요약

Abstract In the published version, we obtain a cheeger inequality of distance regular graphs in terms of the smallest positive eigenvalue of the Laplacian and a value αd. However, we confirm that we need an additional condition for our Cheeger inequality of distance regular graphs: if formula presented >formula presented for t≤αd, then we obtain a Cheeger inequality of distance regular graphs as hΓ< formula presented. © 2015 Elsevier B.V.
