The Moore-Penrose inverse of accretive operators with application to quadratic operator pencils
Fairouz Bouchelaghem, Mohammed Benharrat
We establish some relationships between an m-accretive operator and its Moore-Penorse inverse. We derive some perturbation result of the Moore-Penorse inverse of a maximal accretiv…

A factorization of a quadratic pencils of accretive operators and applications
F. Bouchelaghem, M. Benharrat
A canonical factorization is given for a quadratic pencil of accretive operators in a Hilbert space. Also, we establish some relationships between an m-accretive operator and its M…
