By terms-allowed-in-types capacity, the Logic of Proofs LP includes formulas of the form t : Ï•(t), which have self-referential meanings. In this paper, “prehistoric phenomenaâ€...
In this paper we investigate nonmonotonic `modes of inference'. Our approach uses modal (conditional) logic to establish a uniform framework in which to study nonmonotonic co...
The compositional method, introduced by Feferman and Vaught in 1959, allows to reduce the model-checking problem for a product structure to the model-checking problem for its fact...
—We show that Kripke semantics of modal logic, manifest in the syntactic proof formalism of labeled sequent calculi, can be used to solve three central problems in access control...
