Boundary (topology) - Wikipedia
https://en.wikipedia.org/wiki/Boundary_(topology)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 not belonging to the interior of . An element of the boundary of is called a boundary point of . The term boundary operation refers to finding or taking the ...
