Abstract

Proof systems for classical propositional logic, previously studied only by logicians, now are the subject of intensive research in computer science. There is a special branch of Theoretical Computer Science, named as Proof Complexity Theory, which is concerned with proving lower bounds on the length of proofs in different propositional proof systems and with comparing their efficiency. The study on the complexity of propositional proof systems is motivated by the open question NP=co-NP? This question, closely related to the famous P=NP? problem, can be stated as a problem on the length of proofs in propositional calculus.
