Abstract We prove m ≤ Δ n − (Δ + 1)γ for every graph without isolated vertices of order n , size m , domination number γ and maximum degree Δ ≥ 3. This generalizes a result of Fisher et al., CU‐Denver Tech Rep, 1996] who obtained the given bound for the case Δ = 3. © 1999 John Wiley & Sons, Inc. J Graph Theory 31: 297–302, 1999
