|
Abstract:
伴随不同函数空间上的复对称加权复合算子得到广泛关注,本文致力于研究Fock-Sobolev空间上的复对称加权复合算子
。通过引入复对称算子的概念,运用混合偏导相关公式、分类讨论、数学归纳、反证等方法,得到了
恒不为零以及
的核空间只含零向量,得到了
的特征值都可表示为
形式以及其点谱的具体表达式,并给出了乘法算子
和复合算子
关于共轭算子和再生核函数的关系式。这些发现深化了对Fock-Sobolev空间上的复对称加权复合算子的理解,也为其他函数空间上复对称加权复合算子的研究奠定了理论基础。
Complex symmetric weighted composition operators on different function spaces are widely concerned. In this paper, we study complex symmetric weighted composition operators on Fock-Sobolev spaces. By introducing the concept of complex symmetric operator, using the correlation formula of mixed partial derivative, classification discussion, mathematical induction, inverse proof and other methods, we get
is always non-zero and the kernel space of
only contains zero vector, get the eigenvalues of
