Unbounded Toeplitz operators and finite rank de Branges-Rovnyak spaces

Soumitra Ghara, MD Ramiz Reza, Chaman Kumar Sahu

Motivated by the recent developments of de Branges-Rovnyak spaces, we investigate the function theoretic aspects of finite rank de Branges-Rovnyak spaces $H (B)$ generated by row-va…

Operator Space Structures on $ℓ^{1} (n) .$

Rajeev Gupta, Md Ramiz Reza

We show that the complex normed linear space $ℓ^{1} (n),$ $n > 1,$ has no isometric embedding into $k \times k$ complex matrices for any $k \in N$ and discuss a class of infin…
