Invariant subspaces of powers of some unicellular operators
Sneh Lata, Sushant Pokhriyal, Dinesh Singh
In this paper we study subspaces which are invariant under squares and cubes (separately as well as jointly) of unicellular backward weighted shift operators on a separable Hilbert…
A Simple Proof of Bohr's Inequality
Vern I. Paulsen, Dinesh Singh
The classical inequality of Bohr concerning Taylor coeficients of bounded holomorphic functions on the unit disk, has proved to be of significance in answering in the negative the…
Bohr's Inequality for Non-commutative Hardy Spaces
Sneh Lata, Dinesh Singh
In this paper, we extend the classical Bohr's inequality to the setting of the non-commutative Hardy space associated with a semifinite von Neumann algebra. As a consequence,…
Multivariable Sub-Hardy Hilbert Spaces Invariant under the action of -tuple of Finite Blaschke factors
Sneh Lata, Sushant Pokhriyal, Dinesh Singh
This paper deals with representing in concrete fashion those Hilbert spaces that are vector subspaces of the Hardy spaces $H^p(\bb D^n) \ (1\le p\le \infty)$ that remain invariant…
A Class of Sub-Hardy Hilbert Spaces Associated with Weighted Shifts
Sneh Lata, Dinesh Singh
In this note we study sub-Hardy Hilbert spaces on which the the action of the operator of multiplication by the coordinate function z is assumed to be weaker than that of an isomet…
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 of the form…
