Stone Relation Algebras.
Walter Guttmann · Arch. Formal Proofs · 2017
We study a generalisation of relation algebras in which the underlying Boolean algebra structure is replaced with a Stone algebra. Many theorems of relation algebras generalise with no or small changes. Weighted graphs represented as matrices over extended real numbers form an instance. Relational concepts and methods can thus be applied to weighted graphs. All results are formally verified in Isabelle/HOL.
