Classes of bipartite graphs related to chordal graphs

Brandstadt, A., Classes of bipartite graphs related to chordal graphs, Discrete Applied Mathematics 32 (1991) 51-60. This paper examines in a systematical way connections between chordal, strongly chordal and split graphs and bipartite graphs with chordality properties and introduces a further notion of chordality for bipartite graphs which is called here semichordality and which gives a natural extension of the class of chordal bipartite graphs and is incomparable with the class of perfect elimination bipartite graphs.
