Questions about the branch of combinatorics called graph theory (not to be used for questions concerning the graph of a function). This tag can be further specialized via using it in combination with more specialized tags such as extremal-graph-theory, spectral-graph-theory, algebraic-graph-theory, topological-graph-theory, random-graphs, graph-colorings and several others.

Is the choosability/list chromatic number of a circular arc graph equal to its chromatic num...
In 2003, Prowse and Woodall proved that for graphs $C_n^k$ which are powers of cycles,
$$\chi_\ell(C_n^k) = \chi(C_n^k).$$
They conjectured that this equality holds for the broader class of graphs kno …
