Unification through projectivity
Silvio Ghilardi · Journal of Logic and Computation · 1997
We introduce an algebraic approach to E-unification, through the notions of finitely presented and projective object. As applications and examples, we determine the unification type of varieties generated by a single finite quasi-primal algebra, of distributive lattices and of some other equational classes of algebras corresponding to fragments of intuitionistic logic.
