A New Method of Matrix Spectral Factorization
Gigla Janashia, Edem Lagvilava, Lasha Ephremidze
A new method of matrix spectral factorization is proposed which reliably computes an approximate spectral factor of any matrix spectral density that admits spectral factorization
On Parametrization of Compact Wavelet Matrices
Lasha Ephremidze, Gigla Janashia, Edem Lagvilava
It is given an efficient complete parametrization of wavelet matrices of rank , genus , and degree , which are naturally identified with corresponding polynomial parauni…
An Analytic Proof of the Matrix Spectral Factorization Theorem
L. Ephremidze, G. Janshia, E. Lagvilava
An analytic proof is proposed of Wiener's theorem on factorization of positive definite matrix-functions.
A simple proof of the matrix-valued Fejér-Riesz theorem
L. Ephremidze, G. Janashia, E. Lagvilava
A very short proof of the Fejér-Riesz lemma is presented in the matrix case
