INVERSION GENERALISEE D’OPERATEURS LINEAIRES ET APPROXIMATION DANS LES ESPACES DE BANACH
Keywords:
Opérateur linéaire borné, projection, 1k – inverse, Gk -inverse.Abstract
Soient E et F deux espaces de Banach sur ℂ, A: E→F un opérateur linéaire borné. L'opérateur borné
B: E→F est dit 1k-inverse de A si A(BA)k= A, k∈
