A Bishop-Phelps-Bollobas theorem for disc algebra
Neeru Bala, Jaydeb Sarkar, Aryaman Sensarma
Let represent the open unit disc in . Denote by the disc algebra, and the Banach space of all boun…
Characteristic Functions and Colligations
Neeru Bala, Santanu Dey, Kalpesh J. Haria +1
The characteristic function of row contractions and the characteristic function of liftings of row contractions are multi-analytic operators which are complete invariants up to uni…
Factorization of Characteristic Functions of Iterated Liftings
Neeru Bala, Santanu Dey, M. N. Reshmi
We obtain a factorization of the characteristic function of a contractive two-step iterated lifting in terms of the characteristic functions of constituent liftings of the iterated…
Invariant subspaces of idempotents on Hilbert spaces
Neeru Bala, Nirupam Ghosh, Jaydeb Sarkar
In the setting of operators on Hilbert spaces, we prove that every quasinilpotent operator has a non-trivial closed invariant subspace if and only if every pair of idempotents with…
Representation and normality of -paranormal absolutely norm attaining operators
Neeru Bala
In this article, we give a representation of -paranormal absolutely norm attaining operator. Explicitly saying, every -paranormal absolutely norm attaining ($\mathcal{A…
A Bishop-Phelps-Bollobás theorem for bounded analytic functions
Neeru Bala, Kousik Dhara, Jaydeb Sarkar +1
Let denote the Banach algebra of all bounded analytic functions on the open unit disc and denote by the Banach space of all bounded linear operat…
Idempotent, model, and Toeplitz operators attaining their norms
Neeru Bala, Kousik Dhara, Jaydeb Sarkar +1
We study idempotent, model, and Toeplitz operators that attain the norm. Notably, we prove that if is a backward shift invariant subspace of the Hardy space $H^2(\mat…
A Representation of Hyponormal Absolutely Norm Attaining Operators
Neeru Bala, Ramesh G
In this article, we characterize absolutely norm attaining normal operators in terms of the essential spectrum. Later we prove a structure theorem for hyponormal absolutely norm at…
Weyl's theorem for commuting tuple of paranormal and -paranormal operators
Neeru Bala, G. Ramesh
In this article, we show that a commuting pair of -paranormal operators and with quasitriangular property satisfy the Weyl's theorem-I, that is $$σ_…
Hyperinvariant subspaces for normaloid essential isometric operators
Neeru Bala, Ramesh Golla
In this article, we prove the existence of a non-trivial hyperinvariant subspace for a subclass of compact perturbations of scalar multiple of a partial isometry. Later, we illustr…
Wetting boundaries for ternary high density ratio Lattice Boltzmann Method
Neeru Bala, Marianna Pepona, Ilya Karlin +2
We extend a recently proposed ternary free energy lattice Boltzmann model with high density contrast, by incorporating wetting boundaries at solid walls. The approaches are based o…
Weyl's theorem for paranormal closed operators
Neeru Bala, G. Ramesh
In this article we discuss a few spectral properties of a paranormal closed operator (not necessarily bounded) defined in a Hilbert space. This class contains closed symmetric oper…
Spectral decomposition of normal absolutely minimum attaining operators
Neeru Bala, G. Ramesh
Let be a bounded linear operator defined between complex Hilbert spaces and . We say to be \textit{minimum attaining} if there exists a unit v…
