Jun 19, 2022 · Why should unification in first order logic be limited to unification of first order terms? In first order logic, when unification is defined as a equation, it does not consider unification of formula …

Oct 28, 2020 · 1 In first-order unification, which you seem to be discussing, that is possible assuming X and Z are variables and a is a constant. I'd suggest you check carefully assumptions about …
