We define an algebraic theory of hierarchical graphs, whose axioms characterise graph isomorphism: two terms are equated exactly when they represent the same graph. Our algebra can...

The algebraic theory of quasi-MV algebras, generalisations of MV algebras arising in quantum computation, is by now rather well-developed. Although it is possible to define sever...
In a previous paper, we developed an algebraic theory of threads, interleaving of threads, and interaction of threads with services. In the current paper, we assume that the thread...
We consider CSP from the point of view of the algebraic theory of effects, which classifies operations as effect constructors and effect deconstructors; it also provides a link wit...
We present an algebraic treatment of exception handlers and, more generally, introduce handlers for other computational effects representable by an algebraic theory. These include ...
The impact of types on the algebraic theory of the π-calculus is studied. The type system has capability types. They allow one to distinguish between the ability to read from a c...
Every algebraic theory gives rise to a monad, and monads allow a meta-language which is a basic programming language with sideeffects. Equations in the algebraic theory give rise ...
