Interior Product (⨼) is a mathematical operator used in differential geometry and algebra to denote the interior product (contraction) between a vector and a differential form. This operation reduces the degree of the form by one and is fundamental in calculus on manifolds. The symbol visually represents this specialized product operation.
The Symbol For Interior Product (⨼) is a unicode character in the Basic Multilingual Plane Plane. It is found in the Supplemental Mathematical Operators block and was approved as part of Unicode Version 3.2 in 2002
