HIGHLIGHTS
- who: Domenico Labbate et al. from the , Potenza, Italy have published the research: A Characterization of Graphs with Small Palette Index, in the Journal: Symmetry 2023, 15, 154. of /2023/
- what: The authors characterize all graphs with palette index either 2 or 3 in terms of the existence of suitable decompositions in regular subgraphs. The authors consider a related problem, first introduced, where the problem of minimizing the number of different sets of colors appearing on the edges around each vertex is proposed. The authors provide a complete characterization of graphs with palette index at . . .
