In this paper, we consider the gradient estimates of the positive solutions to the following equation defined on a complete Riemannian manifold where and p is a rational number with where and are positive integer numbers. we obtain the gradient bound of a positive solution to the equation which does not depend on the bounds of the solution and the Laplacian of the distance function on . Our results can be viewed as a natural extension of Yau's estimates on positive harmonic function.

在本文中,我们考虑在完整的黎曼流形上定义的以下方程的正解的梯度估计 哪里 和p是一个有理数与 哪里 和 是正整数。我们获得方程正解的梯度边界,该梯度解不取决于解的边界和距离函数的拉普拉斯算子。我们的结果可以看作是Yau对正谐波函数的估计的自然扩展。
