Density in Approximation Theory
Allan Pinkus
Abstract.
Approximation theory is concerned with the ability to
approximate functions by simpler and more easily calculated
functions. The first question we ask in approximation theory
concerns the possibility of approximation. Is the given
family of functions from which we plan to approximate dense in
the set of functions we wish to approximate? In this work, we
survey some of the main density results and density methods.
