Abstract

By proving an integral formula of the curvature tensor of $E \otimes \textrm{det} \; E$, we observe that the curvature of $E \otimes \textrm{det} \; E$ is very similar to that of a line bundle and obtain certain new Kodaira–Akizuki–Nakano type vanishing theorems for vector bundles. As special cases, we deduce new vanishing theorems for ample, nef and globally generated vector bundles by analytic method instead of the Leray–Borel–Le Potier spectral sequence.
