On Symmetry of Birkhoff-James Orthogonality of Linear Operators on Finite-dimensional Real Banach Spaces
Debmalya Sain, Puja Ghosh, Kallol Paul
We characterize left symmetric linear operators on a finite dimensional strictly convex and smooth real normed linear space which answers a question raised recently…
