Peer reviewedGoetschel, Roy, Jr. – Journal of the American Society for Information Science, 1987
Multivalent relations, inferred as relationships with an added dimension of discernment, are realized as weighted graphs with multivalued edges. A unified treatment of the threshold problem is discussed and a reliability measure is produced to judge various partitions. (Author/EM)

Peer reviewedBeineke, Lowell W. – College Mathematics Journal, 1989
Explored are various aspects of drawing graphs on surfaces. The Euler's formula, Kuratowski's theorem and the drawing of graphs in the plane with as few crossings as possible are discussed. Some applications including embedding of graphs and coloring of maps are included. (YP)
