Varieties of groupoids and quasigroups generated by linear-bivariate polynomials over ring Z_n

Abstract

Some varieties of groupoids and quasigroups generated by linear-bivariate polynomials P (x, y) = a + bx + cy over the ring Z n are studied. Necessary and sufficient conditions for such groupoids and quasigroups to obey identities which involve one, two, three (e.g. Bol-Moufang type) and four variables w.r.t. a, b and c are established. Necessary and sufficient conditions for such groupoids and quasigroups to obey some inverse properties w.r.t. a, b and c are also established. This class of groupoids and quasigroups are found to belong to some varieties of groupoids and quasigroups such as medial groupoid(quasigroup), F-quasigroup, semi automorphic inverse property groupoid(quasigroup) and automorphic inverse property groupoid(quasigroup).
