(n+1)-valued modal implicative semilattices
M.C. Canals Frau, Aldo Victorio Figallo · 2003
The equational class of (n+1)-valued modal implicative semilattices is defined and investigated. These algebras are the natural generalization of three-valued modal implicative semilattices. A characterization of (n+1)-valued Post algebras is given.>
