Note about the upper chromatic number of mixed hypertrees
A mixed hypergraph is a triple H=(X,C,D), where X is the vertex set and each of C,D is a family of subsets of X, the C-edges and D-edges, respectively. A proper k-coloring of H is a mapping c:→[k] such that each C-edge has two vertices with a common color and each D-edge has two vertices with distin...
