Streszczenie
Khabibullin established the best estimate in the Paley problem for a plurisubharmonic (psh) function $u$ of lower order, $0\leq \rho \leq 1$. For $\rho \gt 1$, obtaining a sharp estimate has remained an open question. In this work, we solve this problem. We also provide estimates for the types of characteristic functions $T(r,u)$ and $M(r,u)$. Finally, we compare our results with those of Dahlberg for subharmonic functions and show that the latter are not optimal for psh functions of finite lower order $\rho \gt 1$.
