Cardinality and Representation of Stone Relation Algebras
Walter Guttmann
In relation algebras, which model unweighted graphs, the cardinality operation
counts the number of edges of a graph. We generalise the cardinality axioms to
Stone relation algebras, which model weighted graphs, and study the
relationships between various axioms for cardinality. We also give a
representation theorem for Stone relation algebras.
