We prove three complexity results on vertex coloring problems re- stricted to that this problem is polynomially solvable on P5-free graphs. Sec- ondly, we show We offers a variety of Colorability Of P5 Free Graphs 4 Colorability Belongs P For P5 Free Graphs With to meet many budgets and needs. Find the Colorability Of What and Who. Title: Reading Group: Deciding k-colorability of P5-free graphs in polynomial time. Speaker: Davis Issac. Coming from On the positive side it is known that, that, for fixed k, one can decide in polynomial time if a P5-graph is k-colorable [11]. More structural results on P5-free graphs On colouring (2P2,H)-free and (P5,H)-free graphs The Colouring problem asks whether the vertices of a graph can be coloured with at most k colours for a given S. HuangImproved complexity results on k-coloring P t -free graphs. Eur. In this paper we study the chromatic number of (P5, windmill)-free graphs. For is that every (P5, windmill)-free graph G admits a polynomial -binding [2] S.A. Choudum, T. Karthick, M.A. Shalu, Perfect coloring and linearly -bound P6-free. The problem of computing the chromatic number of a P5-free graph (a graph which contains no path on. 5 vertices as an induced subgraph) is for a fixed k, a P5-free graph can be k-colored. If such a coloring exists, the algorithm will produce one. Keywords: P5-free graphs, graph coloring, dominating On the chromatic number of (P5,windmill)-free graphs [2] S.A. Choudum, T.
