Minimum attaining operators on reducing subspaces: Spectral structure and density
Puspendu Nag, Golla Ramesh
In this article, we introduce and investigate a new subclass of minimum attaining operators on a separable Hilbert space . This class contains the absolutely…
Absolutely minimum attaining Toeplitz and absolutely norm attaining Hankel operators
G. Ramesh, Shanola S. Sequeira
In this article, we completely characterize absolutely norm attaining Hankel operators and absolutely minimum attaining Toeplitz operators. We also improve \cite[Theorem 2.1]{RGSSS…
On the numerical radius of a quaternionic normal operator
G Ramesh
We prove that for a right linear bounded normal operator on a quaternionic Hilbert space (quaternionic bounded normal operator) the norm and the numerical radius are equal. As a co…
Weyl-von Neumann-Berg theorem for quaternionic operators
G. Ramesh
We prove the Weyl-von Neumann-Berg theorem for quaternionic right linear operators (not necessarily bounded) in a quaternionic Hilbert space: Let be a right linear normal (need…
