SUBDIRECTLY IRREDUCIBLE QUASI-MODAL ALGEBRAS
Sergio Arturo Celani · 2005
Abstract. In this paper we give suitable notions of congruences and subdirectly irreducible algebras for the class of quasi-modal algebras introduced in [1]. We also prove some characterizations of subdirectly irreducible algebras following the similar results given by G. Sambin [5] for modal algebras. 1.
