Abstract
We define the concept of approximate Ïâ-orthogonality preserving mapping between normed linear spaces and give some characterizations for a linear mapping to be approximately Ïâ-orthogonality preserving. Moreover, we show that every approximately Ïâ-orthogonality preserving linear mapping is necessarily a scalar multiple of an almost isometry.
