Projections in operator ranges
Gustavo Corach, Alejandra Maestripieri, Demetrio Stojanoff
If $\H$ is a Hilbert space, is a positive bounded linear operator on $\cH$ and $\cS$ is a closed subspace of $\cH$, the relative position between $\cS$ and $A^{-1}(\cS \orto)$…
Weighted generalized inverses, oblique projections and least squares problems
Gustavo Corach, Alejandra Maestripieri
A generalization with singular weights of Moore-Penrose generalized inverses of closed range operators in Hilbert spaces is studied using the notion of compatibility of subspaces a…
Metric and homogeneous structure of closed range operators
Gustavo Corach, Alejandra Maestripieri, Mostafa Mbekhta
Let $\CR$ be the set of all bounded linear operators between Hilbert spaces $\cH, \cK$. This paper is devoted to the study of the topological properties of $\CR$ if certain natural…
Bilateral Shorted Operators and Parallel Sums
Jorge Antezana, Gustavo Corach, Demetrio Stojanoff
In this paper we study shorted operators relative to two different subspaces, for bounded operators on infinite dimensional Hilbert spaces. We define two notions of complementabili…
