We define a variant of the standard Kripke semantics for intuitionistic logic, motivated by the connection between constructive logic and the Medvedev lattice. We show that while...
Abstract. PROTEIN (PROver with a Theory Extension INterface) is a PTTPbased first order theorem prover over built-in theories. Besides various standardrefinements knownformodelelim...
Completion is a general paradigm for applying inferences to generate a canonical presentation of a logical theory, or to semi-decide the validity of theorems, or to answer queries....
We study logical principles connecting two relations: independence, which is known as nondeducibility in the study of information flow, and functional dependence. Two different e...
