Birkhoff-James orthogonality to a subspace of operators defined between Banach spaces

Arpita Mal, Kallol Paul

This paper deals with study of Birkhoff-James orthogonality of a linear operator to a subspace of operators defined between arbitrary Banach spaces. In case the domain space is ref…

Characterization of $k -$ smooth operators between Banach spaces

Arpita Mal, Kallol Paul

We study $k -$ smoothness of bounded linear operators defined between arbitrary Banach spaces. As an application, we characterize $k -$ smooth operators defined from $ℓ_{1}^{n}$ to an a…

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…
