Abstract

CHAHBI, Abdellatif  and  KABBAJ, Samir. On linear maps that preserve G-partial-isometries in Hilbert space. Proyecciones (Antofagasta) [online]. 2014, vol.33, n.4, pp.405-413. ISSN 0716-0917.  http://dx.doi.org/10.4067/S0716-09172014000400004.

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.

Keywords : Linear preserver; Jordan homo-morphisms; Operators on spaces with an indefinite metric; partial-isometric operators.
