Abstract

In this paper we develop a systematical way to compute the integral \(\int _{\mathbb {P}^{r-1}} \frac{|\sum _{i=1}^{r}f_iX_i|^2(\sum h_{i\bar{j}}X_i\bar{X}_j)^{k}}{(\sum _{j=1}^p|\sum _{i=1}^{r} g_{ji} X_i|^2)^{r+k+1}}h_0\,\mathrm{d}V_X \) on the projective space \(\mathbb {P}^{r-1}\). Then by this average technique we can link Skoda’s two division theorems together and by the algebraic verification of the fundamental inequality applied to the division theorems we can derive some vanishing theorems.
