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

Shamim Sohel, Debmalya Sain, Kallol Paul

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