In mathematics, particularly in measure theory and set theory, a **ring of sets** is a collection of sets that is closed under certain operations. More formally, a family \\( R \\) of sets is called a ring if it satisfies the following properties: 1. **Closure under intersection**: If \\( A \\) and \\( B \\) are in \\( R \\), then \\( A \\cap B \\) is also in \\( R \\).
