Basic positively closed classes in three-valued logic
S. S. Marchenkov, A. V. Chernyshev Lomonosov Moscow State University
Abstract:
Basic positively closed classes are intersections of positively precomplete classes. We prove that three-valued logic contains exactly 79 basic positively closed classes. Each class is described in terms of endomorphism semigroups.
Keywords:
three-valued logic, basic positively closed class.
