In the work, we obtain an effective criterion of the stability of the partial indices for matrix polynomials under an arbitrary sufficiently small perturbation. Verification of the stability is reduced to calculation of the ranks for two explicitly d

We consider the Wiener–Hopf factorization problem for a matrix function that is completely defined by its first column: the succeeding columns are obtained from the first one by means of a finite group of permutations. The symmetry of this matrix f

In this paper, a new definition of a reduced Padé approximant and an algorithm for its computation are proposed. Our approach is based on the investigation of the kernel structure of the Toeplitz matrix. It is shown that the reduced Padé approximan

Let D+ be amultiply connected domain bounded by a contour Γ, let D- be the complement of D+ ∪ Γ in ℂ̄ = ℂ ∪, and a(t) be acontinuous invertible matrix-valued function on which can be meromorphically extended into the open disconnected set

In the work the uniform convergence of rows of the Padé approximants for a meromorphic function a(z) is studied. The complete description of the asymptotic behavior of denominators Qn(z) of the Padé approximants is obtained for the (λ−1)th row.

In the computer algebra system Maple, we have created a package MinimalRealization to solve the minimal realization problem for a discrete-time linear time-invariant system. The package enables to construct the minimal realization of a system startin

A new method is proposed for calculating the partial indices and the Wiener-Hopf factorization of analytic matrix-valued functions. It has computational advantages with respect to the method proposed by the author earlier. The new method is used to f
