In mathematics, the empty set, denoted by the symbol ∅ or {} (curly braces with no elements), is a set that contains no elements at all. It is considered a subset of every set and serves as the foundational concept in set theory. The empty set is important for defining various mathematical concepts and operations, such as unions and intersections. Its existence allows for a more comprehensive understanding of set relationships and properties.
