SEMIGROUPS GENERATED BY PARTITIONS
Oleksiy A. Dovgoshey · International Electronic Journal of Algebra · 2019
Let X be a nonempty set and X^2 be the Cartesian square of X. Some semigroups of binary relations generated by partitions of X^2 are studied. In particular, the algebraic structure of semigroups generated by the finest partition of X^2 and, respectively, by the finest symmetric partition of X^2 are described.
