U+29D3 "⧓" Black Bowtie is a typographic symbol in the Mathematical Operators block, representing a solid black shape that resembles a bowtie or two opposing filled triangles or chevrons meeting at a central point. It is used in mathematical notation, particularly in logic and set theory, to denote operations like the Sheffer stroke or NAND operator, as well as in knot theory and other specialized fields to indicate specific configurations or relationships. Its design allows it to function as a concise visual marker in technical diagrams and formulas, distinct from other similar symbols like the white bowtie (U+29D4) by its filled appearance.
