Some Tauberian Theorems with Applications to Approximation Theory

In this note we state some results, mostly without proof, conce ing the comparison of integral inequalities of a certain type. As ?" cations of these results we can deduce from a unified source theor of approximation theory due to Jackson, Bernstein, and Zygn comparison theorems for moduli of smoothness of different or and theorems of Hardy and Littlewood… (More)
