In topology and mathematics in general, the boundary of a subset S of a topological space X is the set of points which can be approached both from S and from the outside of S. More precisely, it is the set of points in the closure of S not belonging to the interior of S. An element of the boundary of S is called a boundary point of S. The term boundary operation refers to finding or taking the boundary of a set. Boundary of a topological subspace: if S is a subspace of a topological space, then its boundary, denoted ∂, is the set difference betwen the closure and the interior of S. [3] 1.
