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…

The Weak differentiability of norm and a generalized Bhatia-Šemrl Theorem

Saikat Roy

We completely characterize the weak differentiability (or, in other words Gateaux differentiability) of the norm in the spaces of bounded multilinear maps. Also, we obtain a multil…
