In this paper, we will discuss some applications of almost surjective -isometry mapping, one of them is in Lorentz space ( , -space). Furthermore, using some classical theorems of * -topology and concept of closed subspace -complemented, for every almost surjective -isometry mapping f : X → Y, where Y is a reflexive Banach space, then there exists a bounded linear operator T : Y → X with ‖ ‖ ≤ such that ‖ ( ) − ‖ ≤ 4 for every ∈ .
