Subdifferential of the $B (H, K)$ norm, and approximate orthogonality

Priyanka Grover, Krishna Kumar Gupta, Susmita Seal

We present an expression for the right hand derivative of the $B (H, K)$ norm generalizing the result for $K = H$ in [D. J. Ke $c ˇ$ ki$\grav…

Geometric characterization of Generalized Property (II)

Sudeshna Basu, Susmita Seal

Let $A$ be a compatible collection of bounded subsets of a Banach space $X$ . In this paper, we introduce the notion of $A$ -Property (II) and prove that $X$ has…

Geometry of the unit ball of $L (X, Y^{*})$

T. S. S. R. K. Rao, Susmita Seal

In this work we study the geometry of the unit ball of the space of operators $L (X, Y^{*})$ , by considering the projective tensor product $X \otimes^_{π} Y$ as a predual.…
