In this paper, we investigate the vanishing theorems for harmonic p-forms on a locally conformally flat Riemannian manifold. Specifically, we present a vanishing theorem for them without the need for scalar curvature conditions, when the integral of the traceless Ricci tensor satisfies a suitable bound. Furthermore, we provide another theorem under the condition of nonpositive scalar curvature, which improves and extends previous results.
In this paper, we show some vanishing theorems for harmonic p-forms on a locally conformally flat Riemannian manifold. In the concrete, provided that the integral of the traceless Ricci tensor has a suitable bound, we obtain a vanishing theorem for them without any scalar curvature conditions. Another theorem is also given under the condition on nonpositive scalar curvature, which improves and extends the ones previous.
