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

The paper investigates when the Calkin algebra of a Banach space fails or satisfies ball covering properties, showing failure for spaces with a 1‑unconditional basis and establishi…

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…
