U+2962 "⥢" Leftwards Harpoon with Barb Up Above Leftwards Harpoon with Barb Down Unicode Character

Unicode Version 17.0

U+2962 "⥢" Leftwards Harpoon with Barb Up Above Leftwards Harpoon with Barb Down is a specialized mathematical symbol used primarily in the notation of category theory and algebra to represent a specific type of natural transformation or a pair of related, opposing arrows pointing left. It combines two harpoons, one above the other, that share a single shaft, with the top harpoon having its barb pointing up and the bottom harpoon having its barb pointing down, both oriented leftward. This glyph visually indicates a bidirectional or reversible relationship within a diagram, often signifying a map that is both a left adjoint and a right adjoint under certain conditions or a 2‑cell in a higher‑dimensional categorical structure. As part of the Supplemental Arrows‑A block, it provides a precise visual cue for complex functional dependencies where simple arrows are insufficient.
