Haar space explained
In approximation theory, a Haar space or Chebyshev space is a finite-dimensional subspace
of
, where
is a
compact space and
either the real numbers or the complex numbers, such that for any given
there is exactly one element of
that approximates
"best", i.e. with minimum distance to
in
supremum norm.
