Boundary mathematics
In topology and mathematics in general, the boundary of a subset S of a topological space X 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. … See more There are several equivalent definitions for the boundary of a subset $${\displaystyle S\subseteq X}$$ of a topological space $${\displaystyle X,}$$ which will be denoted by $${\displaystyle \partial _{X}S,}$$ See more For any set $${\displaystyle S,\partial S\supseteq \partial \partial S,}$$ where $${\displaystyle \,\supseteq \,}$$ denotes the superset with equality holding if and only if the boundary of $${\displaystyle S}$$ has no interior points, which will be the case for example if See more Characterizations and general examples A set and its complement have the same boundary: A set See more • See the discussion of boundary in topological manifold for more details. • Boundary of a manifold – Topological space that locally resembles Euclidean space See more
