Approximation Theory

Approximation Theory is a branch of numerical analysis that studies how functions, data, or mathematical objects can be approximated by simpler or more tractable constructs, typically using finite-dimensional subspaces or discrete representations, to achieve a desired level of accuracy with minimal error.
