本文给出例子 ,说明离散算子本征投影一致有界推不出其本征幂零一致有界 。
Two examples are given which show that the uniform boundedness of eigenprojections of a discrete operator does not deduce the uniform boundedness of eigennilpotents of the operator,and the uniform boundedness of eigennilpotents does not deduce the uniform boundedness of the powers of eigennilpotents.$$$$
