Theorem 2
Let $H$ be a monoid and $r$ a weak ideal system on $H$. Then the set of all r-ideals of $H$ is a lattice w.r.t. following operations multiplication: $(X,Y)\mapsto (XY)_r$ for all $X,Y \in I_r(H)$, join: $\bigvee \Gamma := (\bigcup \Gamma)_r$ for all $\Gamma \subseteq I_r(H)$, meet: $\bigwedge \Gamma := \bigcap \Gamma$ for all $\Gamma \subseteq I_r(H)$, where $\bigcup
