چکیده
|
We introduce the circle-uniqueness of pythagorean orthogonality in normed linear spaces and show that pythagorean orthogonality is circle-unique if and only if the underlying space is strictly convex. further related results providing more detailed relations between circle-uniqueness of pythagorean orthogonality and the shape of the unit sphere are also presented. © 2014 senlin wu et al.
