Invariance Under Bounded Analytic Functions

Ajay Kumar, Niteesh Sahni, Dinesh Singh

In a recent paper, M. Raghupathi has extended the famous theorem of Beurling to the context of subspaces that are invariant under the class of subalgebras of $H^{\infty}$ of the form…

$λ$ -tensor product of operator spaces

Vandana Rajpal, Ajay Kumar

We propose a theory of $λ$ -tensor product of operator spaces which extends the theory of Blecher-Paulsen and Effros-Ruan for the operator space projective tensor product \cite{blec…

Sub-Hardy Hilbert spaces on the circle and torus

Ajay Kumar, Niteesh Sahni, Dinesh Singh

Sahni and Singh settled a problem posed by Yousefi & Hesameddini by generalizing their main result with a simple proof in the setting of sub-Hilbert spaces in $H^{2} (T)$ . In this pap…
