Integral With Leftwards Arrow With Hook Symbol
⨗ denotes an integral sign combined with a leftwards arrow and hook for specialized mathematical notation.
U+2A17
⨗ is a mathematical symbol named “integral with leftwards arrow with hook.” It’s used when notation needs to mark a specific integral-related operation or direction. You can copy it directly or use its code point in fonts and programming contexts.
Integral With Leftwards Arrow With Hook Symbol Meaning
⨗ is an integral-like operator (Unicode: U+2A17) that combines the integral sign with a leftwards arrow and a hook. In mathematical writing, arrow-and-hook variants are typically used to communicate additional structure beyond a standard integral—such as directionality, transformation, or an emphasized operator behavior in a particular formal system. Because this is a specialized Unicode operator, its exact interpretation depends on the conventions of the document or field using the notation. When you’re matching existing notation, the safest approach is to follow the surrounding definitions in your source text or typesetting guidelines.
Common uses
- •Typeset specialized integral operators in mathematical documents
- •Replicate existing formal notation from papers, lecture slides, or textbooks
- •Label equations in STEM writing where arrow direction matters
- •Create consistent symbols in technical documents using Unicode math fonts
- •Use in digital content (blogs, apps, or notes) that require a precise operator glyph
