摘要
运用Hankel向量的方法求解一类带重点的退化Nevanlinna-Pick插值问题，在问题有解时给出解的具体表示式．已有的一些结论也被简化和推广．
Hankel vector approach is used to solve a class of degenerate Nevanlinna-Pick problems with multiple nodes. An explicit formula of the solutions in given when the NP problem is solvable. Such a treatment yields some generalizations and simpler proofs of relative known results as well.
