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…
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…
Admissible fundamental operators
Tirthankar Bhattacharyya, Sneh Lata, Haripada Sau
Let and be two bounded operators on two Hilbert spaces. Let their numerical radii be no greater than one. This note investigate when there is a -contraction such…
The Feichtinger Conjecture and Reproducing Kernel Hilbert Spaces
Sneh Lata, Vern I. Paulsen
We prove two new equivalences of the Feichtinger conjecture that involve reproducing kernel Hilbert spaces. We prove that if for every Hilbert space, contractively contained in the…
A Finite Multiplicity Helson-Lowdenslager-De Branges Theorem
Sneh Lata, Meghna Mittal, Dinesh Singh
This paper proves two theorems. The first of these simplifies and lends clarity to the previous characterizations of the invariant subspaces of , the operator of multiplication…
