Abstract
Let L be an rlattice, i.e., a modular multiplicative lattice that is compactly generated, principally generated, and has greatest element 1 compact. We consider certain subsets of L consisting of “regular elements”: $L_f = \left\{ 0 \right\} \cup \left\{ A \right. \in \left. L \right\left. {(0:A) = 0} \right\},L_{sr} = \left\{ 0 \right\} \cup \left\{ A \right. \in \left. L \right$ there is a compact element $X \leqslant A$ with $\left. {(0:X) = 0} \right\},L_r = \left\{ 0 \right\} \cup \left\{ A \right. \in \left. L \right$ there is a principal element $X \leqslant A{\text{ with }}\left. {(0:X) = 0} \right\},{\text{ and }}L_{rg} = \left\{ 0 \right\} \cup \left\{ A \right. \in \left. L \rightA = \bigvee _\alpha X_\alpha {\text{ where each }}X_\alpha $ is a principal element with (0:X_{\alpha })=0\} . The first three subsets L_{f}, L_{sr}, and L_{r} are augmented filters $\mathcal{L}^0 $ on L, i.e., $\mathcal{L}^0 = \mathcal{L} \cup \left\{ 0 \right\}{\text{ where }}\mathcal{L}$ is a multiplicatively closed subset of $L$ with $A\in $\mathcal{L}$ and $B\geq A$ with $B\in L$ implies $B\in $\mathcal{L}$ and hence are sublattices of $L$ closed under multiplication. We first consider the more general situation of augmented filters on $L.$ These results are then applied to study the four previously defined subsets for $L$ an $r$lattice or Noether lattice (i.e., an $r$lattice with ACC). Finally, we give a brief discussion of how the results for augmented lattices can be applied to subsets of $L$ which are “regular” with respect to an $L$module.
