Abstract:

A house is the graph that consists of an induced 4-vertex cycle and a single vertex with precisely two adjacent neighbors on the cycle. The Borodin-Kostochka Conjecture states that for each graph G with increment Delta(G) >= 9, we have chi(G) < max{ increment Delta(G) - 1, omega(G)}. We show that this conjecture holds for {P-2 U P-3, house}-free graphs. (c) 2023 Elsevier B.V. All rights reserved.
