Some Closed Classes of Three-Valued Logic Generated by Periodic Symmetric Functions
A. V. Mikhailovich · arXiv (Cornell University) · 2016
Closed classes of three-valued logic generated by periodic symmetric funtions that equal $1$ in tuples from $\{1,2\}^n$ and equal $0$ on the rest tuples are considered. Criteria for bases existence and finite bases existence for these classes is obtained.
