关于耗散算子不动点的唯一性及其点态遍历性──兼评Chidume的文章

On Uniqueness of Fixed Points and Pointwise Ergodicict for Dissipative Operators:A Note on a Paper by Chidume

我们证明了Ｃ．Ｅ．Ｃｈｉｄｕｍｅ在文献［１］（Ｂｕｌｌ．Ａｕｓｔｒａｌ．Ｍａｔｈ．Ｓｏｃ．１９９０，４２：２１～３１）中给出的主要定理是错误的，并作了完善与修正．

We show that the main theorem obtained by C.E.Chidume in reference[1](Bull.Austral.Math.Soc.1990,42:21￣31)is not valid,and make some improvements and complements.
