Abstract
Montassier et al. showed that every planar graph without cycles of length at most five at distance less than four is 3-colorable [A relaxation of of Havel’s 3-color problem, Inform. Process. Lett. 107 (2008) 107–109]. Borodin, Montassier and Raspaud asked in [Planar graphs without adjacent cycles of length at most seven are 3-colorable, Discrete Math. 310 (2010) 167–173]: is every planar graph without adjacent cycles of length at most five 3-colorable? In this note, we show that every planar graph without cycles of length at most five at distance less than two is 3-colorable.
