We show how to reason about “step-indexed” logitions in an abstract way, avoiding the tedious, error-prone, and proof-obscuring step-index arithmetic that seems superficially...

Realizing Default Logic over Description Logic Knowledge Bases
Abstract. We consider a realization of Reiter-style default logic on top of description logic knowledge bases (DL-KBs). To this end, we present elegant transformations from default...

Higher-Order Logic Programming as Constraint Logic Programming
Higher-order logic programming (HOLP) languages are particularly useful for various kinds of metaprogramming and theorem proving tasks because of the logical support for variable ...

EPR-Based Bounded Model Checking at Word Level
We propose a word level, bounded model checking (BMC) algorithm based on translation into the effectively propositional fragment (EPR) of firstorder logic. This approach to BMC al...

Avoiding Deontic Explosion by Contextually Restricting Aggregation
Abstract. In this paper, we present an adaptive logic for deontic conflicts, called P2.1r , that is based on Goble’s logic SDLaPe—a bimodal extension of Goble’s logic P that...
