摘要
本文根据广义极值原理给出次调和函数的若干定理,据此我们可直接将一些命题从紧致的情况推广到完备的情况,同时也纠正一些论文因引用广义极原理不当所造成的错误。
In this paper,some theorems about superharmonic functions are given byusing the generalized maximal principle due to S.T.Yau.From these we im-mediately obtain some results,which not only hold in compactness but also incompleteness.At the same time,we point out some mistakes in [4],[5],[6]in using the principle.
