Linear maps on $L (ℓ_{p}^{n}, ℓ_{p}^{m})$ , $(p \in {1, \infty})$ preserving parallel pairs

Arpita Mal

Two vectors $x, y$ of a Banach space are said to form a parallel (resp. triangle equality attaining or TEA) pair if $∥ x + λ y ∥ = ∥ x ∥ + ∥ y ∥$ holds for some scalar $λ$ with $∣ λ ∣ = 1$ (re…

Joint numerical radius of Tuples: Extreme points, subdifferential set and Gateaux derivative

Arpita Mal

Suppose $Z$ is the space of all tuples of operators on a finite-dimensional Banach space endowed with the joint numerical radius norm. We obtain the structure of the extr…

Min-max relations for tuples of operators in terms of component spaces

Arpita Mal

For tuples of compact operators $T = (T_{1}, \dots, T_{d})$ and $S = (S_{1},$ $\dots, S_{d})$ on Banach spaces over a field $F$ , considering the joint $p$ -operator…
