Gn. Chen et Yj. Hu, A unified treatment for the matrix Stieltjes moment problem in both nondegenerate and degenerate cases, J MATH ANAL, 254(1), 2001, pp. 23-34
This paper presents a unified method for the solution of the matrix Stieltj
es moment problem in both the nondegenerate and degenerate cases, based on
the use of our recent investigation of the matrix Hamburger moment problem.
As a by-product, a complete solution of the matrix Nevanlinna-Pick interpo
lation problem in the class of the matrix-valued Stieltjes functions is der
ived as well. (C) 2001 Academic Press.
