In 1968, Vizing conjectured that, if G is a Δ-critical graph with n vertices, then α (G) ≤ frac(n, 2), where α (G) is the independence number of G. In this note, we apply Vizing and Vizing-like adjacency lemmas to this problem and obtain better bounds for Δ ∈ {7, ..., 19}. © 2008 Elsevier B.V. All rights reserved
