It can signify exponentiation, the bitwise XOR operator, string concatenation [citation needed], and control characters in caret notation, among other uses. In regular expressions , the caret is used to match the beginning of a string or line; if it begins a character class, then the inverse of the class is to be matched.
The V sign, a symbol representing peace among other things The vertically reflected symbol, ∧, is a wedge , and often denotes related or dual operators. The ∨ symbol was introduced by Russell and Whitehead in Principia Mathematica , where they called it the Logical Sum or Disjunctive Function .
