In topology, the **closure** of a set refers to a fundamental concept related to the limit points and the boundary of that set within a given topological space. Specifically, the closure of a set \\( A \\) in a topological space \\( (X, \\tau) \\) is the smallest closed set that contains \\( A \\).
