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_…
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…
