smoothness on polyhedral Banach spaces
Subhrajit Dey, Arpita Mal, Kallol Paul
We characterize smoothness of an element on the unit sphere of a finite-dimensional polyhedral Banach space. Then we study smoothness of an operator $T \in \mathbb{L}(\ell_…
Characterization of k-smoothness of operators defined between infinite-dimensional spaces
Arpita Mal, Subhrajit Sey, Kallol Paul
We characterize smoothness of bounded linear operators defined between infinite-dimensional Hilbert spaces. We study the problem in the setting of both finite and infinite-dime…
Characterization of extreme contractions through smoothness of operators
Arpita Mal, Kallol Paul, Subhrajit Dey
We characrterize extreme contractions defined between \ finite-dimensional polyhedral Banach spaces using - smoothness of operators. We also explore weak L-P property, a recentl…
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…
