| Popis: | Let $${\mathscr {H}}$$ be a complex Hilbert space and $${\mathscr {B}}({\mathscr {H}})$$ the algebra of all bounded linear operators on $${\mathscr {H}}$$. We give the concrete forms of surjective continue unital linear maps from $${\mathscr {B}}({\mathscr {H}})$$ onto itself that preserves G-quasi-isometric operators. |
