Title
Complexity of Coloring Graphs without Paths and Cycles.
Abstract
Let Pt and Cℓ denote a path on t vertices and a cycle on ℓ vertices, respectively. In this paper we study the k-coloring problem for (Pt,Cℓ)-free graphs. Bruce et al. (2009), and Maffray and Morel (2012) have proved that 3-colorability of P5-free graphs has a finite forbidden induced subgraphs characterization, while Hoàng et al. (2015) have shown that k-colorability of P5-free graphs for k≥4 does not. These authors have also shown, aided by a computer search, that 4-colorability of (P5,C5)-free graphs does have a finite forbidden induced subgraph characterization.
