For description logics with existential restrictions, the size of the least common subsumer (lcs) of concept descriptions may grow exponentially in the size of the concept descrip...
Proof nets are a parallel syntax for sequential proofs of linear logic, firstly introduced by Girard in 1987. Here we present and intrinsic (geometrical) characterization of proof...
We present a constructive authorization logic where the meanings of connectives are defined by their associated inference rules. This ensures that the logical reading of access c...
A compositional Petri net based semantics is given to a simple pointer-manipulating language. The model is then applied to give a notion of validity to the judgements made by conc...
