Abstract: We prove that for any $ n\in\mathbb{Z}\backslash\{0\}$, $ p>1$ and any weight $ w$ from the Muckenhoupt $ A_p$ class, the norm of the $ n$-th power of the Ahlfors-Beurling operator $ T$ on the weighted Lebesgue space $ L^p(w)$ is majorized by $ C(p) \vert n\vert^3 [w]_p^{\operatorname{max}\{1,1/(p-1)\}}$, where $ [w]_p$ is the $ A_p$ characteristic of $ w$. We apply this estimate for a result concerning the spectrum of $ T$ on $ L^p(w)$.
