Resumen de On linear maps that preserve G-partial-isometries in Hilbert space

Abdellatif Chahbi, Samir Kabbaj

• Let Ti be a complex Hilbert space and B(TT) the algebra of all bounded linear operators on H. We give the concrete forms of surjec-tive continue unital linear maps from B(TT) onto itself that preserves G-partial-isometric operators.
