| Abstrakt: | Unifiability of terms (and formulas) and structural completeness in the variety of relation algebras RA and in the products of modal logic S5 is investigated. Non- unifiable terms (formulas) which are satisfiable in varieties (in logics) are exhibited. Consequently, RA and products of S5 as well as representable diagonal-free n-dimensional cylindric algebras, RDfn , are almost structurally complete but not structurally complete. In case of S5n a basis for admissible rules and the form of all passive rules are provided. |
