Phase Factors in Singular Value Decomposition and Schmidt Decomposition [PDF]
arXiv, 2022 In singular value decomposition (SVD) of a complex matrix A, the singular vectors or the eigenvectors of AA{\dag} and A{\dag}A are unique up to complex phase factors. Thus, the two unitary matrices in SVD are unique up to diagonal matrices of phase factors, the phase-factor matrices.

An algorithm for J-spectral factorization of certain matrix functions [PDF]
arXiv, 2021 The problems of matrix spectral factorization and J-spectral factorization appear to be important for practical use in many MIMO control systems. We propose a numerical algorithm for J-spectral factorization which extends Janashia-Lagvilava matrix spectral factorization method to the indefinite case.

Score Predictor Factor Analysis as model for the identification of single-item indicators [PDF]
arXiv, 2020 Score Predictor Factor Analysis (SPFA) was introduced as a method that allows to compute factor score predictors that are -- under some conditions -- more highly correlated with the common factors resulting from factor analysis than the factor score predictors computed from the common factor model.
