exterior

In mathematics, specifically in topology,
the interior of a subset S of a topological space X is the union of all subsets of S that are open in X.
A point that is in the interior of S is an interior point of S.
The interior of S is the complement of the closure of the complement of S.
In this sense interior and closure are dual notions.
The exterior of a set S is the complement of the closure of S; it consists of the points that are in neither the set nor its boundary.
The interior, boundary, and exterior of a subset together partition the whole space into three blocks (or fewer when one or more of these is empty).
The interior and exterior of a closed curve are a slightly different concept; see the Jordan curve theorem.
