The 5 Colour Theorem in Isabelle/Isar
Based on an inductive definition of triangulations, a theory of undirected planar graphs is developed in Isabelle/HOL. The proof of the 5 colour theorem is discussed in some detai...

A Proposal for a Formal OCL Semantics in Isabelle/HOL
Abstract We present a formal semantics as a conservative shallow embedding of the Object Constraint Language (OCL). OCL is currently under development within an open standardizatio...

Representation and Reasoning with Disjunctive Temporal Constraints
We show the expressiveness provided by a Labelled point-based metric model for specifying and reasoning about complex disjunctive temporal constraints. The model allows us to mana...
