摘要
利用以迁移理论为背景提出的u-标算子的概念,研究u-标算子的拟仿射变换和解析变换,并给出一系列非古典标型谱的u-算子的例子.
The sulfficinet(and necessary)conditions of u-scalar operators are given;And a series ofexamples obtained by the use of quasi-affine transformations and analytic transformations of u-scalaroperators are discussed,which are not spectral operators of scalar type but u-scalar operators.
