U+2A0C "⨌" Quadruple Integral Operator Unicode Character
Unicode Version 17.0
⨌
U+2A0C "⨌" Quadruple Integral Operator is a mathematical symbol used to denote integration over a four-dimensional region or volume, extending the concept of single, double, and triple integrals into higher dimensions. It is part of the Supplemental Mathematical Operators block and is typically encountered in advanced calculus, physics, and engineering contexts, such as when calculating hypervolumes or integrating over spacetime in certain theoretical frameworks. The symbol visually resembles four integral signs joined together, making it distinct from the standard single integral or the more common double and triple integral operators.
