Closed classes of the three-valued logic generated by systems containing symmetric functions
A. V. Mikhailovich · Moscow University Mathematics Bulletin · 2012
Closed classes of functions of the three-valued logic whose generating systems include nonmonotone symmetric functions taking values in the set {0, 1} are studied. It is shown that in some cases the problems of existence of a basis and existence of a finite basis can be reduced to similar problem for reduced generating systems.
