A Formal Temporal Semantics for Microsoft Project based on Allen's Interval Algebra
Process modelling systems are complex and difficult to compare. A key attribute of any process modelling formalism or tool is time which involves how it handles and represents tem...

Capture-avoiding substitution as a nominal algebra
Substitution is fundamental to the theory of logic and computation. Is substitution something that we define on syntax on a case-by-case basis, or can we turn the idea of substitut...

The Algebra of Multi-Agent Dynamic Belief Revision
We refine our algebraic axiomatization in [8,9] of epistemic actions and epistemic update (notions defined in [5,6] using Kripke-style semantics), to incorporate a mechanism for d...

Constructions of Orthonormal Lattices and Quaternion Division Algebras for Totally Real Number Fields
Abstract. We describe some constructions of orthonormal lattices in totally real subfields of cyclotomic fields, obtained by endowing their ring of integers with a trace form. We...
