In mathematics, the ''n''-dimensional complex coordinate space (or complex ''n''-space) is the set of all ordered ''n''-tuples of complex numbers. It is denoted , and is the ''n''-fold Cartesian product of the complex plane with itself. Symbolically, : or : The variables are the (complex) coordinates on the complex ''n''-space. Complex coordinate space is a vector space over the complex numbers, with componentwise addition and scalar multiplication. The real and imaginary parts of the coordinates set up a bijection of with the real coordinate space . With the standard Euclidean topology, is a topological vector space over the complex numbers. A function on an open subset of complex ''n''-space is holomorphic if it is holomorphic in each complex coordinate separately. Several complex variables is the study of such holomorphic functions in ''n'' variables. More generally, the complex ''n''-space is the target space for holomorphic coordinate systems on complex manifolds. ==See also== * Coordinate space 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Complex coordinate space」の詳細全文を読む スポンサード リンク
