A simple method of factorization of S-matrices into jost matrices

1994
As is well known, the Jost function plays an important role in scattering theory, and particulary in the inverse scattering problem. One of the methods of obtaining Jost function F(k) is to solve Riemann-Hilbert problem for the half-plane: $$ {F_ + }\left( k \right) = {S^{ - 1}}\left( k \right)F - \left( k \right),\quad \operatorname{Im} k = 0 ...

Factorable generalized Hausdorff matrices

2010
An ordinary conservative Hausdorff matrix \((*)\) \(\binom n k \Delta^{n-k}\mu_k\) \((0 \leq k \leq n),\) where \(\Delta^0 \mu_k: = \mu_k\), \(\Delta \mu_k:= \mu_k-\mu_{k+1}\), is defined by its moment sequence \(\mu_k = \int^1_0 t^k \,d \chi (t)\). The conservative matrices \(H = (h_{nk} : 0 \leq k \leq n)\) under consideration have the exponent \(k\)

Coprime Factorizations of Multivariate Rational Matrices

Mathematics of Control, Signals, and Systems, 2000
Coprime factorization is a well-known issue in one-dimensional systems theory, having many applications in realization theory, balancing, controller synthesis, etc. Generalization to systems in more than one independent variable is a delicate matter: First of all, several non-equivalent coprimeness notions have to be taken into account. Even worse, the
