Barycentric algebras have seen widespread application in the modeling of convex sets, semilattices, and quantum mechanics. Recently, they were developed further to encompass Boolea...
Nested Pushdown Trees are unfoldings of pushdown graphs with an additional jump-relation. These graphs are closely related to collapsible pushdown graphs. They enjoy decidable µ-c...
The system of Peirce’s existential graphs is a diagrammatic version of first order logic. To be more precisely: As Peirce wanted to develop a logic of relatives (i.e., relations...
We consider BioAmbients, a calculus for specifying biological entities and for simulating and analysing their behaviour. We extend BioAmbients to take quantitative information into...
Overhearing is an indirect interaction type that enacts agents to listen to direct interactions among other agents without taking explicit part in the exchanges. In this paper, we ...
