我们在具有完备的Nevanlinna-Pick(CNP)核的Hilbert函数空间中研究了稠定(但可能是无界)乘法算子。对于这样一个稠密定义的算子T,Tand的域是逆地包含在环境空间中的再生核Hilbert空间。我们研究了这些空间的几个方面,特别是的定义域,它们可以看作是单位圆盘上经典的deBrange-Rovnyak空间的类似。
We examine densely defined (but possibly unbounded) multiplication operators in Hilbert function spaces possessing a complete Nevanlinna–Pick (CNP) kernel. For such a densely defined operatorT, the domains ofTandare reproducing kernel Hilbert spaces contractively contained in the ambient space. We study several aspects of these spaces, especially the domain of, which can be viewed as analogs of the classical deBranges–Rovnyak spaces in the unit disk.
