- W2353996903 abstract "The realizable problems of Boolean matrices and the relations between realizable Boolean matrices and the chromatic number of graphs are discussed.This paper first gives some necessary and sufficient conditions that Boolean matices are realizable,investigates the properties of realizable Boolean matrices,then proves that the content of a realizable Boolean matrix is the chromatic number of graph which is generated by the realizable Boolean matrix,and shows that the dual matrix of adjacency matrix of a simple graph is realizable and its content is an upper bound for the chromatic number of the same graph." @default.
