On subspaces of $ℓ_{\infty}$ and extreme contraction in $L (X, ℓ_{\infty}^{n})$

Shamim Sohel, Debmalya Sain, Kallol Paul

We investigate different possiblities of subspaces of the space $ℓ_{\infty}$ in terms of whether the subspaces are polyhedral or not. We further study finite-dimensional subspac…

Birkhoff-James Orthogonality and Its Local Symmetry in Some Sequence Spaces

Babhrubahan Bose, Saikat Roy, Debmalya Sain

We study Birkhoff-James orthogonality and its local symmetry in some sequence spaces namely $ℓ_{p},$ for $1 \leq p \leq \infty$ , $p \neq = 2$ , $c$ , $c_{0}$ and $c_{00}$ . Using the characte…
