O


The letter O is used for a number of different purposes in mathematics. The double-struck O is sometimes used to represent octonions. The symbols O(x) (sometimes called the O-symbol, O-notation, or "big-O") and o(x) (sometimes called "little-o") are a type of asymptotic notation collectively known as Landau symbols.
