S. Das, H. Dutta, Degree of approximation of signals in certain Lipschitz classes by the Zweier–Euler product summability method of Fourier series, Math. Methods ...

Inequalities in mathematical analysis constitute a fundamental tool for establishing bounds and approximations for a diverse array of functions. They underpin many theoretical results while also ...

Empirically obtained approximations to the polygamma functions ψ(n)(x) and their associated accuracies are presented. These simple functions are quite accurate, this accuracy increasing with X and ...
