One-sided principal ideals in the direct product of two semigroups

Imrich Fabrici — 1993

Mathematica Bohemica

A necessary and sufficient condition is given for a) a principal left ideal $L (s, t)$ in $S \times T$ to be equal to the direct product of the corresponding principal left ideals $L (s) \times L (t)$ , b) an $ℒ$ -class $L_{(s, t)}$ to be equal to the direct product of the corresponding $ℒ$ -classes $L_{s} \times L_{t}$ .
