The two-variable-fragment L驴 2 of first order logic is the set of formulas that do not contain function symbols, that possibly contain equality, and that contain at most two variables. This paper shows how resolution theorem-proving techniques can be used to provide an algorithm for deciding whether any given formula in L驴 2 is satisfiable. Previous resolution-based techniques could deal only with the equality-free subset L2 of the two-variable fragment.
