Title: Proving Unprovability
Authors: M. Tiomkin
PDFCS0478.pdf
Abstract: A formal proof system for unprovability in the predicate calculi is developed. This system is shown to be complete with respect to the logic of finite structures. Its applications may be extending the "negation by failure" of Prolog, preventing infinite loops in a deductive data base or Prolog. or proving formulas in a nonmonotonic (default) logic.
