The point x is called a boundary point of E if for any ε>0 the ε-neighborhood (x −ε,x +ε) contains both a point in E and another point not in E. Remark. Every interior point of the set E must belong to E. Every exterior point of E must not belong to E. Any particular boundary point may or may not be in E.
