Weighted pseudoinversion with singular weights

The paper reviews the development of the theory of weighted pseudoinversion. Weighted pseudoinverse matrices with singular weights are determined and investigated. Theorems of the existence and uniqueness of these matrices are provided. Weighted pseudoinverses with singular weights are related to weighted normal pseudosolutions. Weighted pseudoinverses with singular weights are represented in terms of coefficients of characteristic polynomials of symmetric and symmetrizable matrices. Their expansions into matrix power series and products and limit representations are obtained. Decompositions of weighed pseudoinverses are determined on the basis of the obtained weighed singular decomposition of matrices with singular weights. © 2016, Springer Science+Business Media New York.
