Regular open set: Art, Properties & Examples

A subset S {\displaystyle S} of a topological space X {\displaystyle X} is called a regular open set if it is equal to the interior of its closure; expressed symbolically, if Int ⁡ ( S ¯ ) = S {\displaystyle \operatorname {Int} ({\overline {S}})=S} or, equivalently, if ∂ ( S ¯ ) = ∂ S , {\displaystyle \partial ({\overline {S}})=\partial S,} where Int ⁡ S…
