Streszczenie
For $1\leq p,q \leq \infty $, we prove that the convolution operator generated by the Cantor–Lebesgue measure on the circle ${{\mathbb T}}$ is a contraction whenever it is bounded from $L^p ({{\mathbb T}} )$ to $L^q ({{\mathbb T}} )$. We also give a condition on $p$ which is necessary if this operator maps $L^p ({{\mathbb T}})$ into $L^2 ({{\mathbb T}} )$.
