Paper: Rigid E-unifiability is DEXPTIME-complete (at LICS 1994)

Authors: Jean Goubault


Proves that rigid E-unifiability, a decision problem invented by Gallier et al. (1987) to extend first-order tableaux-like proof procedures to first-order logic with equality, is DEXPTIME-complete; and that, when restricted to monadic terms, it is PSPACE-complete
