We introduce G-relative-pushouts (GRPO) which are a 2-categorical generalisation of relative-pushouts (RPO). They are suitable for deriving labelled transition systems (LTS) for p...
We present pmlB, a programming language that includes primitive sets and associated operations. The language is equipped with a precise type discipline that statically captures dy...
We design an efficient algorithm that maximizes the sum of array elements of a subarray of a two-dimensional array. The solution can be used to find the most promising array porti...
In previous work [14] I introduced a generalised notion of coalgebra that is capable of modelling binary methods as they occur in object-oriented programming. An important problem...
The Ambient Calculus offers many ways in which processes can interact and be observed. In the context of Levi and Sangiorgi's Safe Mobile Ambients (SA), the extra co-capabili...
