Quasiregular and Baer lattices - I

Abstract

Let ]]> ]]> ]]> ]]> ]]> ]]> ]]> ]]> ]]> ]]> ]]> ]]> ]]> ]]> ]]> L$ be a compactly generated multiplicative lattice with 1 compact in which every finite product of compact elements is compact and $u\in L$ denote a radical element. We generalize the concepts, such as, Baer element, closed element etc. Using these concepts, we generalize many results proved by~D.~D. Anderson, C. Jayaram and others. In this paper we provide the modified definition for regular lattices and find their characterizations. Also we give abstract versions of many known results of ideal theory of commutative rings. Some of the important results are: \bigskip {\sc Result 1.} In $S$, suppose a finite product of compact elements is compact. Then the following statements on $S$ are equivalent. \begin{itemize} \item $S$ is a regular lattice. \item Every semiprimary element of $S$ is maximal. \item Every semiprimary element of $S$ is minimal prime. \item Every primary element of $S$ is minimal prime. \item Every primary element of $S$ is maximal. \item Every prime element of $S$ is maximal. \item Every prime element of $S$ is minimal prime. \end{itemize} \bigskip {\sc Result 2.} Let $S$ be a compactly generated multiplicative lattice (not necessarily, 1 compact). Then $S$ is a sublattice of a regular lattice iff $0=\sqrt 0$ in $S$.
