摘要
利用常微分方程的两点边值问题的比较定理,给出了完备黎曼流形上拉普拉斯算子的一个新的比较定理。
A new laplacian comparison result on complete Riemann Manifold is given by means of the comparison results of two point boundary ralue problems for second order ordinary differentied equations. An improvement of the previous estimate has been made via relaxing the curature assumption in the generalized maximum principle due to paper and .
