论文摘要
在本说明中，我们提供了De Branges-Rovnyak内核的新属性。作为主要定理，表明如果相应的Schur类函数的内部不繁琐，则De Branges-Rovnyak内核的指数严格确定。
In this note, we give a new property of de Branges-Rovnyak kernels. As the main theorem, it is shown that the exponential of de Branges-Rovnyak kernel is strictly positive definite if the inner part of the corresponding Schur class function is nontrivial.
