Discretization. Direct and Inverse Theorems of Approximation Theory
What may be referred to as discretization is replacing an integral by its Riemann integral sums, substituting a function by the interpolation series, passing from an infinite-dimensional space (of functions) to a finite-dimensional space (of polynomials, splines, etc.), and the like
