Several Complex Variables

The theory of functions of several complex variables is the branch of mathematics dealing with functions

f(z1, z2, ..., zn)

on the space Cn of n-tuples of complex numbers. As in complex analysis, which is the case n = 1 but of a distinct character, these are not just any functions: they are supposed to be analytic, so that locally speaking they are power series in the variables zi.

Equivalently, as it turns out, they are locally uniform limits of polynomials; or locally square-integrable solutions to the n-dimensional Cauchy–Riemann equations.

Famous quotes containing the words complex and/or variables:

    By “object” is meant some element in the complex whole that is defined in abstraction from the whole of which it is a distinction.
    John Dewey (1859–1952)

    The variables are surprisingly few.... One can whip or be whipped; one can eat excrement or quaff urine; mouth and private part can be meet in this or that commerce. After which there is the gray of morning and the sour knowledge that things have remained fairly generally the same since man first met goat and woman.
    George Steiner (b. 1929)
