Delta-ring: Definition & Overview

In mathematics, a non-empty collection of sets R {\displaystyle {\mathcal {R}}} is called a δ-ring (pronounced "delta-ring") if it is closed under union, relative complementation, and countable intersection. The name "delta-ring" originates from the German word for intersection, "Durchschnitt", which is meant to highlight the ring's closure under…
