U+2A03 "⨃" N-Ary Union Operator with Dot Unicode Character
Unicode Version 17.0
⨃
U+2A03 "⨃" N-Ary Union Operator with Dot is a mathematical symbol used primarily in set theory and lattice algebra to denote a generalized union operation that includes an additional constraint or modification indicated by the dot. It represents the union of a collection of sets, similar to the standard n-ary union operator (⋃), but the dot serves as a diacritical mark to specify a variant meaning, such as a disjoint union, a restricted union, or a union with a particular property defined in the context. This character is part of the Supplemental Mathematical Operators block and is employed in advanced mathematical notation where precise distinctions between different types of collective union operations are necessary.
