Direct sums and summability of the Szlenk index

Szymon Draga, Tomasz Kochanek

We prove that the $c_{0}$ -sum of separable Banach spaces with uniformly summable Szlenk index has summable Szlenk index, whereas this result is no longer valid for more general direc…

Reducing the polynomial-like iterative equations order and a generalized Zoltán Boros' problem

Szymon Draga, Janusz Morawiec

We present a technique for reducing the order of polynomial-like iterative equations; in particular, we answer a question asked by Wenmeng Zhang and Weinian Zhang. Our method invol…

On a Zoltán Boros' problem connected with polynomial-like iterative equations

Szymon Draga, Janusz Morawiec

We determine all continuous solutions $g : I \to I$ of the polynomial-like iterative equation $g^{3} (x) = 3 g (x) - 2 x$ , where $I \subset R$ is an interval. In particular, we obta…
