We give a categorial characterization of how labelled deduction systems for logics with a propositional basis behave under unconstrained fibring and under fibring that is constrai...
Fibring is a metalogical constructor that permits to combine different logics by operating on their deductive systems under certain natural restrictions, as for example that the t...
This paper proposes a Compiled Labelled Deductive System, called ACCLDS, for reasoning about role-based access control in distributed systems, which builds upon Massacci’s tablea...
We give a sound and complete labeled natural deduction system for an interesting fragment of CTL∗ , namely the until-free version of BCTL∗ . The logic BCTL∗ is obtained by re...
