加权Dirichlet空间上加权复合算子的Fredholm性
Fredholm Weighted Composition Operators on the Weighted Dirichlet Space
【摘要】 本文给出了加权Dirichlet空间D_β上有界Fredholm加权复合算子的刻画,作为推论分别给出了D_β上加权复合算子是有界可逆的和酉算子的刻画.
【Abstract】 In this paper,the bounded,Predholm weighted composition operator on weighted Dirichlet space D_β is studied.As corollaries,the conditions for a weighted composition operator on D_β to be bounded,invertible and unitary are characterized respectively.
