N-ary Square Intersection Operator Symbol
⨅ denotes an n-ary square intersection operator in mathematical notation.
U+2A05
The symbol ⨅ (U+2A05) is a math operator used to represent intersections over multiple terms. It’s commonly typeset in formal equations and can be copied directly for use in documents or code.
N-ary Square Intersection Operator Symbol Meaning
⨅ is the “n-ary square intersection operator” (Unicode U+2A05). In mathematical writing, it indicates an intersection that applies to an arbitrary number of elements or sets (n-ary intersection). The “square” in the name refers to the visual form of the operator, distinguishing it from other intersection symbols used in different contexts. You’ll most often see ⨅ in texts that emphasize generalizing intersection across multiple indexed objects, such as families of sets or predicates. Like many Unicode math operators, its exact rendering depends on the font and math typesetting engine.
Common uses
- •Expressing intersection across a family of sets with an index (n-ary intersection).
- •Writing formal definitions involving intersections over multiple conditions or components.
- •Annotating mathematical notes where the intersection applies to more than two objects.
- •Building LaTeX-like expressions in editors that support Unicode math symbols.
- •Prototyping formulas in web content, documentation, or slides where MathML/Unicode is used.
