P 4-Colorings and P 4-Bipartite Graphs
A vertex partition of a graph into disjoint subsets V i s is said to be a P 4-free coloring if each color class V i induces a subgraph without chordless path on four vertices (denoted by P 4). Examples of P 4-free 2-colorable graphs (also called P 4-bipartite graphs) include parity...
