[Tex/LaTex] ISO: cross product


ISO norms specify a standard symbol for cross product?

I found in many books of mathematics the


operator, while in physics it seems widely used the


(or \land or another similar symbol?) operator.

Which is the correct one according to ISO norms?

The standard ISO 80000-2, “Mathematical signs and symbols to be used in the natural sciences and technology”, specifies that the symbol for vector product (commonly known as cross product, too) is “×” MULTIPLICATION SIGN U+00D7. This corresponds to \times in LaTeX.

The “wedge” symbol “∧” denotes “logical and” by that standard and in common practice in formal logic. Using it for other purposes is thus nonstandard and potentially misleading.
