Positive closed classes in the three-valued logic
Theoretical premises are formulated and a way is determined to construct the positive classification of the k-valued logic functions set. All 194 positive closed classes in the three-valued logic are found. The description is given both by means of endomorphism semigroups and by means of finding the positive bases.
