0x22C6

0x22C6 refers to the Unicode code point U+22C6, a character in the Mathematical Operators block. The glyph is the star operator (⋆), a stylized star used as a binary operator in various mathematical contexts. Its decimal code point is 8902, and it is supported in modern fonts and software that render Unicode math symbols.

In usage, the star operator denotes a variety of binary operations depending on the discipline. It is commonly associated with star products in noncommutative geometry and deformation quantization, where it represents a specific associative product on functions or symbols. In other contexts, the symbol may stand for a specialized multiplication, convolution-like operation, or other domain-specific binary operation. Because its meaning is not fixed across fields, readers should consult the notation conventions of the relevant subject area.

In typesetting, U+22C6 is accessible in common math environments. In TeX/LaTeX, the glyph can be produced in math mode with the \star command. In HTML and other web contexts, it can be represented by a numeric character reference (for example, ⋆) or by inserting the glyph in environments that support Unicode.

Relation to similar symbols: the star operator is distinct from the asterisk () used for the Kleene star in automata theory and computing, and from other star-like symbols such as the black star (U+2605). The exact interpretation of ⋆ depends on the mathematical or theoretical framework in which it appears.
