Differentiability of the operator norm on $ℓ_{p}$ spaces

Sreejith Siju

In this paper, we present a characterization of strong subdifferentiability of the norm of bounded linear operators on $ℓ_{p}$ spaces, $1 \leq p < \infty$ . Furthermore, we prove that…

Ball Covering Property on Operators and Calkin Algebra

Sreejith Siju, Bentuo Zheng

A Banach space $X$ is said to have the ball covering property (BCP) if the unit sphere of $X$ can be covered by countably many open balls $B (x_{i}, r_{i})$ with $r_{i} \leq ∥ x_{i} ∥$ for e…

Analytic primes, $M$ -ideals, and $p$ -sets in $H^{\infty} (D)$

Deepak K. D, Jaydeb Sarkar, Sreejith Siju

We investigate the structure of $p$ -sets, $M$ -ideals, and a newly introduced notion of analytic primes in $H^{\infty} (D)$ , where $H^{\infty} (D)$ denotes the Banach al…

Ball proximinality of $M$ -ideals of compact operators

C. R. Jayanarayanan, Sreejith Siju

In this article, we prove the proximinality of closed unit ball of $M$ -ideals of compact operators. We also prove the ball proximinality of $M$ -embedded spaces in their biduals. Mo…
