Polar decomposition of oblique projections
(Elsevier Science Inc., 2010-10)
The partial isometries and the positive semidefinite operators which appear as factors of polar decompositions of bounded linear idempotent operators in a Hilbert space are characterized.

A note on the differentiable structure of generalized idempotents
(Versita, 2013-02)
For a fixed n > 2, we study the set of generalized idempotents, which are operators satisfying Tn+1 = T. Also the subsets † , of operators such that Tn−1 is the Moore–Penrose pseudo-inverse of T, and , of operators such ...
A inversa generalizada de uma matriz e aplicações
(Universidade Estadual Paulista (Unesp), 2022-10-14)
A resolução de sistemas lineares tem aplicação nos mais diversos campos da ciência. Em geral, as resoluções de sistemas lineares envolvendo a inversa de uma matriz estão restritas às matrizes quadradas e não singulares. O ...

Products of orthogonal projections and polar decompositions
(Elsevier Science Inc, 2010-12)
We characterize the sets X of all products P Q, and Y of all products P QP, where P, Q run over all orthogonal projections and we solve the problems arg min{kP − Qk : (P, Q) ∈ Z}, for Z = X or Y. We also determine the polar ...

Hamiltonian formulation of teleparallel gravity
(American Physical Society, 2016-11)
The Hamiltonian formulation of the teleparallel equivalent of general relativity is developed from an ordinary second-order Lagrangian, which is written as a quadratic form of the coefficients of anholonomy of the orthonormal ...
