内部 (位相空間論)
1. Interior (topology)In mathematics, specifically in topology, the interior of a set S of points of a topological space consists of all points of S that do not belong to the boundary of S. A point that is in the interior of S is an interior point of S. Equivalently the interior of S is the complement of the closure of the complement of S. In this sense interior and closure are dual notions.
