Deterministic and random approximation by the combination of algebraic polynomials and trigonometric polynomials
Fourier approximation plays a key role in qualitative theory of deterministic and random differential equations. In this paper, we will develop a new approximation tool. For an mm-order differentiable function ff on [0,10,1], we will construct an mm-degree algebraic polynomial Pm{P}_{m} depending on...
