We consider simple digital curves in a 3D orthogonal grid as special polyhedrally bounded sets. These digital curves model digitized curves or arcs in three-dimensional euclidean ...
While Game Semantics has been remarkably successful at g, often in a fully abstract manner, a wide range of features of programming languages, there has to date been no attempt at...
We show that simultaneous rigid E-unification, or SREU for short, is decidable and in fact EXPTIME-complete in the case of one variable. This result implies that the fragment of i...

This paper proposes a formalism for reasoning about distributed object-oriented computations. The formalism is an extension of Milner’s CCS with the notion of local time. It allo...
The theorem of factorisation forests shows the existence of nested factorisations -- a la Ramsey -- for finite words. This theorem has important applications in semigroup theory, a...
