\begin{equation} \begin{split} \sum_{j=1}^{p}\left[\frac{1}{\frac{1}{p-\alpha(j-1)}(1-\frac{1}{p-\alpha(j-1)})^{p-j}} \cdot\frac{1}{(\theta-\frac{1}{p-\alpha(j-1)})(p-j+1)}\right] \\ \end{split} \end{equation} $p$ is a finite constant, $\theta$ is a constant between 0 to 1, $\alpha$ is a constant making $\theta-\frac{1}{p-\alpha(j-1)}$ bigger than 0.
Please help me calculate this sum, or find the upper and lower bound(especially the upper bound).
Thank you very much!
