On power series with positive coefficients
Some classical inequalities of Hardy and Littlewood are generalized initiated by the idea of M. Mateljevic and M. Pavlovic. Roughly speaking, the special functions \(x^ \alpha\) and \(x^ p\) appearing in the inequalities of Hardy and Littlewood are replaced by more general functions \(\alpha (x)\) and \(\Phi (x)\), furthermore, the so-called ``blocking method'' is used to get some slight improvement in the classical cases, too.
