On approximate orthogonality and symmetry of operators in semi-Hilbertian structure
Jeet Sen, Debmalya Sain, Kallol Paul
The purpose of the article is to generalize the concept of approximate Birkhoff-James orthogonality, in the semi-Hilbertian structure. Given a positive operator on a Hilbert…

Orthogonality and Numerical radius inequalities of operator matrices
Arpita Mal, Kallol Paul, Jeet Sen
We completely characterize Birkhoff-James orthogonality with respect to numerical radius norm in the space of bounded linear operators on a complex Hilbert space. As applications o…
