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…

A perturbation result of m-accretive linear operators in Hilbert spaces
Mohammed Benharrat
A new sufficient condition is given for the sum of linear m-accretive operator and accretive operator one in a Hilbert space to be m-accretive. As an application, an extended resul…
