Title
Maximum number of colorings of (2k, k2)-graphs
Abstract
Let ℱ2k, k2 consist of allsimple graphs on 2k vertices and k2edges. For a simple graph G and a positive integerλ, let PG(λ) denotethe number of proper vertex colorings of G in at mostλ colors, and let f(2k, k2,λ) =max{PG(λ):Gεℱ2k,k2}.We prove that f(2k, k2, 3) =PKk,k(3) and Kk,k is theonly extremal graph. We also prove that f(2k,k2, 4) = (6+o(1))4k ask ➝ ∞. © 2007 Wiley Periodicals,Inc. J Graph Theory 56: 135148, 2007
