 Uniform module

A nonzero module is uniform if every pair of nonzero submodules has nonzero intersection. Equivalently, every nonzero submodule is an essential submodule. A right Noetherian domain is uniform as a right module: if $aA\cap bA=0$ for nonzero $a,b$, the right ideals $b^{i}aA$, $i\ge 0$, form an infinite direct sum, contradicting the ascending chain condition.

A uniform module is a concept from the field of module theory in algebra, particularly related to the study of Abelian groups and rings. It refers to a type of module that has a certain uniformity property regarding its submodules.
