On numerical radius and Crawford number attainment sets of a bounded linear operator
Debmalya Sain, Arpita Mal, Pintu Bhunia +1
We completely characterize the Crawford number attainment set and the numerical radius attainment set of a bounded linear operator on a Hilbert space. We study the intersection pro…

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 smooth operators between Banach spaces
Arpita Mal, Kallol Paul
We study smoothness of bounded linear operators defined between arbitrary Banach spaces. As an application, we characterize smooth operators defined from to an a…
