We employ some results about continued fraction expansions of Herglotz-Nevanlinna functions to characterize the spectral data of generalized indefinite strings of Stieltjes type. In particular, this solves the corresponding inverse spectral problem through explicit formulas.
我们运用一些关于赫尔戈洛茨 - 内万林纳函数连分数展开的结果来刻画斯蒂尔杰斯型广义不定弦的谱数据。特别地,这通过显式公式解决了相应的逆谱问题。
