Abstract.
Let H be a separable complex Hilbert space and \({\mathcal{G}}_\infty (H)\) be the Grassmannian of closed subspaces with infinite dimension and codimension. We show that every order preserving bijective transformation of \({\mathcal{G}}_\infty (H)\) is induced by an invertible bounded semi-linear operator.
