# Atomic lattice

From Encyclopedia of Mathematics

2020 Mathematics Subject Classification: *Primary:* 06B [MSN][ZBL]

A lattice with a zero $0$ in which, for each non-zero element $a$, there exists an atom $p\leq a$, that is, $0 < p$ and $x < p \Rightarrow x=0$

A lattice is **atomistic** if it is atomic and every element is a join of some finite set of atoms.

Some authors use "atomic" to denote what is here defined as "atomistic".
