Triangle‐free graphs that do not contain an induced subdivision of K4 are 3‐colorable

Abstract

We show that triangle‐free graphs that do not contain an induced subgraph isomorphic to a subdivision of are 3‐colorable. This proves a conjecture of Trotignon and Vušković [J. Graph Theory. 84 (2017), no. 3, pp. 233–248].
