We introduce a natural deduction formulation for the Logic of Proofs, a refinement of modal logic S4 in which the assertion PA is replaced by [[s]]A whose intended reading is “s...
Deontic logic is appropriate to model a wide variety of legal arguments, however this logic suffers form certain paradoxes of which the so-called Chisholm is one of the most notor...
The new generic scheme CFLP(D) has been recently proposed in [24] as a logical and semantic framework for lazy constraint functional logic programming over a parametrically given ...
The event calculus is a logic programming formalism for representing events and their effects especially in database applications. This paper presents the use of the event calculus...
