On the Tight Chromatic Bounds for a Class of Graphs without Three Induced Subgraphs

28 Jul 2016  ·  Dhurandhar Medha ·

Here we prove that a graph without some three induced subgraphs has chromatic number at the most equal to its maximum clique size plus one. Further we show that the bounds are tight and give examples to show that each of the three forbidden subgraphs is necessary in the hypothesis...
