Interior Product Symbol
The ⨼ symbol (INTERIOR PRODUCT) is a mathematical operator used in notation involving contraction/interior operations.
U+2A3C
⨼ is the Unicode character named “INTERIOR PRODUCT” (U+2A3C). It’s commonly used as a math operator in specialized notation. Below you’ll find copy-friendly variations and practical ways to use it in documents and code.
Interior Product Symbol Meaning
⨼ is a mathematical symbol whose Unicode name is “INTERIOR PRODUCT” (U+2A3C). As an operator, it appears in contexts where an “interior product” (sometimes described as a contraction of one object with another) is written in mathematical typography. Because this character is primarily a technical notation mark rather than a widely recognized punctuation or decorative glyph, its meaning is best understood from the surrounding formula or the notation system you’re using. If you’re not already working in that specific math convention, the symbol may not render clearly in all fonts, so testing in your target environment is recommended.
Common uses
- •Typing math notation in plain text where Unicode operators are preferred
- •Labeling or documenting variables/operators in technical write-ups
- •Using the symbol in LaTeX/Unicode-aware workflows for equation drafts
- •Copy/pasting into documents, slides, or notes that support Unicode math symbols
- •Including the character in developer documentation or code comments that mention it
