On map**s which approximately preserve angles
SMS Nabavi Sales - Aequationes mathematicae, 2018 - Springer
In this paper, we study map**s, which approximately preserve angles between inner
product spaces. We also introduce a notion of angle in normed spaces. The notion of angle …

We consider a concept of angle in normed spaces which preserves isosceles orthogonality
and approximate isosceles orthogonality and then we investigate linear map**s which …
