Abstract

In this paper the notion of quasi-hard determinative formulas is introduced and the proof complexities of such formulas are investigated. For some class of quasi-hard determinative formulas the same order lower and upper bounds for the length of proofs are obtained in several proof systems, basing on disjunctive normal forms (conjunctive normal forms).
