Streszczenie
It is well known that if $\varphi (t) \equiv t $, then the system $ \{ \varphi ^{n}(t)\}_{n=0}^{\infty }$ is not a Schauder basis in $ L_{2}[0,1] $. It is natural to ask whether there is a function $\varphi $ for which the power system $ \{ \varphi ^{n}(t)\}_{n=0}^{\infty }$ is a basis in some Lebesgue space $L_{p}$. The aim of this short note is to show that the answer to this question is negative.
