A remark on a result on odd colorings of planar graphsPradhan, Dinabandhu (Avtor) Sharma, Vaishali (Avtor) Škrekovski, Riste (Avtor) coloringodd coloringplanar graphsA proper $k$-coloring of a graph is said to be odd if every non-isolated vertex has a color that appears an odd number of times on its neighborhood. Miao et al. (2024) [2] claimed that every planar graph without adjacent $3$-cycles is odd $7$-colorable and every triangle-free planar graph without intersecting $4$-cycles is odd $5$-colorable. Here, we point out that their published proof contains a fundamental flaw which affects the validity of the main results.20262026-02-03 09:01:09Članek v reviji179007sl
