This paper introduces a variant of clausal normal form tableaux that we call “hyper tableaux”. Hyper tableaux keep many desirable features of analytic tableaux while taking advantage of the central idea from (positive) hyper resolution, namely to resolve away all negative literals of a clause in a single inference step. Another feature of the proposed calculus is the extensive use of universally quantified variables. This enables new efficient forward-chaining proof procedures for full first order theories as variants of tableaux calculi.
