It is well known that if φ(t) ≡ t, then the system ${φⁿ(t)}_{n=0}^{∞}$ is not a Schauder basis in L₂[0,1]. It is natural to ask whether there is a function φ for which the power system ${φⁿ(t)}_{n=0}^{∞}$ 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.
