Zero (complex Analysis) - Existence of Zeros

Existence of Zeros

The fundamental theorem of algebra says that every nonconstant polynomial with complex coefficients has at least one zero in the complex plane. This is in contrast to the situation with real zeros: some polynomial functions with real coefficients have no real zeros. An example is f(x) = x2 + 1.

Famous quotes containing the words existence of and/or existence:

    Analysis brings no curative powers in its train; it merely makes us conscious of the existence of an evil, which, oddly enough, is consciousness.
    Henry Miller (1891–1980)

    Nothing exists except by virtue of a disequilibrium, an injustice. All existence is a theft paid for by other existences; no life flowers except on a cemetery.
    Rémy De Gourmont (1858–1915)
