Complex coordinate space
Inmathematics,then-dimensionalcomplex coordinate space(orcomplexn-space) is the set of all orderedn-tuplesofcomplex numbers,also known ascomplex vectors.The space is denoted,and is then-foldCartesian productof thecomplex planewith itself. Symbolically, or The variablesare the (complex) coordinates on the complexn-space.
Complex coordinate space is avector spaceover the complex numbers, with componentwise addition andscalar multiplication.The real and imaginary parts of the coordinates set up abijectionofwith the 2n-dimensionalreal coordinate space,.With the standardEuclidean topology,is atopological vector spaceover the complex numbers.
A function on an open subset of complexn-space is holomorphic if it isholomorphicin each complex coordinate separately.Several complex variablesis the study of such holomorphic functions innvariables. More generally, the complexn-space is the target space for holomorphic coordinate systems oncomplex manifolds.
