... A formula is in prenex form if it is of the form Q1 x1 .Q2 x2 . . . . Qn xn .ψ (possibly with n = 0) where each Qi is a quantifier (either ∀ or ∃) and ψ is a quantifier-free formula . Proposition For any formula of first-order logic, there exists an equivalent formula in prenex form. Proof. Such a p ...

... An exhaustive procedure for solving the PSAT problem is to try systematically all of the ways to assign True and False to the atoms in the formula, checking the assignment to see if all formulas have value True under that assignment. If there are n atoms in the formula, there are 2n different assign ...

... generated by a set of proper 2-element groupoids is finitely based in the sense of equational logic. Theorem 1 generalizes earlier results of the author. In [2] we showed (as a special case) that |=f is f.b. for any f . In [3] we claimed T that |=f ∩ |=f ∗ is f.b. where f ∗ is the dual of f . In [4] ...
