On Nonnegative Moore-Penrose Inverses of Perturbed Matrices
Journal of Applied Mathematics, 2013 Nonnegativity of the Moore-Penrose inverse of a perturbation of the form is considered when . Using a generalized version of the Sherman-Morrison-Woodbury formula, conditions for to be nonnegative are derived.

Some Results on Generalized Inverse of Intuitionistic Fuzzy Matrices
Fuzzy Information and Engineering, 2014 In this paper, pseudo-similar intuitionistic fuzzy matrix (IFM) is defined with some properties of pseudo-similar and semi-similar IFMs studied. Here it is shown that, the pseudo-similarity relation preserve idempotency and regularity for the IFMs. After

Singular matrices possessing the triangle property
Special MatricesIt is known that the inverse of an invertible real square matrix satisfying the triangle property is a tridiagonal matrix. In this note, results that may be considered as analogues of this assertion are obtained for the Moore-Penrose inverse and the ...

Parallelism between Moore-Penrose inverse and Aluthge transformation of operators
, 2018 In this paper we study some parallelisms between ?-Aluthge transform and binormal operators on a Hilbert space via the Moore-Penrose inverse. Moreover, we give some applications of these results on the Lambert multiplication operators acting on L2(?).

Efficient GMM estimation with singular system of moment conditions
Statistical Theory and Related Fields, 2020 Standard generalised method of moments (GMM) estimation was developed for nonsingular system of moment conditions. However, many important economic models are characterised by singular system of moment conditions.

A generalization of the Moore-Penrose inverse related to matrix subspaces of C(nxm)
, 2010 A natural generalization of the classical Moore-Penrose inverse is presented. The so-called S-Moore-Penrose inverse of a m x n complex matrix A, denoted by As, is defined for any linear subspace S of the matrix vector space Cnxm.

Parallel computing methods to determine parametric generalized inverse matrices
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 The relevancy of the work is conditioned by the necessity to determine effectively the Moore-Penrose generalized parametric inverse matrices which are quite often encountered when solving non-autonomous linear systems of finite equations, optimal control

On the mean and dispersion of the Moore-Penrose generalized inverse of a Wishart matrix [PDF]
, 2019 The Moore-Penrose inverse of a singular Wishart matrix is studied. When the scale matrix equals the identity matrix the mean and dispersion matrices of the Moore-Penrose inverse are known. When the scale matrix has an arbitrary structure no exact results
