Characterization and recognition of edge intersection graphs of trichromatic hypergraphs with finite multiplicity in the class of split graphs
A hypergraph is called k-chromatic if its vertex set can be partitioned into at most k pairwise disjoint subsets when each subset has no more than two common vertices with every edge of the hypergraph. The multiplicity of a pair of vertices in a hypergraph is the number of hypergraph edges containin...
