U+2A30 "⨰" Multiplication Sign with Dot Above Unicode Character
Unicode Version 17.0
⨰
U+2A30 "⨰" Multiplication Sign with Dot Above is a mathematical symbol used primarily in advanced algebra and abstract notation to denote a specific binary operation, often distinct from ordinary multiplication or the cross product. It combines the standard multiplication sign (×) with a dot above, which can indicate a modified or decorated product, such as a twisted or deformed multiplication in contexts like noncommutative algebra or representation theory. This symbol is particularly useful in fields where precise distinctions between different types of multiplicative operations are necessary, and it is encoded in the Unicode standard to support clear and consistent typesetting in digital documents.
