A Note on Approximating the Symplectic Spectrum
V. B. Kiran Kumar, Anmary Tonny
The symplectic eigenvalues play a significant role in finite mode quantum information theory, and Williamson normal form proves to be a valuable tool in this area. Understanding th…
An Order Relation between Eigenvalues and Symplectic Eigenvalues of a Class of Infinite-Dimensional Operators
Tiju Cherian John, V. B. Kiran Kumar, Anmary Tonny
In this article, we obtain some results in the direction of ``infinite dimensional symplectic spectral theory". We prove an inequality between the eigenvalues and symplectic eigenv…
Stability in Non-Normal Periodic Jacobi Operators: Advancing Börg's Theorem
Krishna Kumar G., V. B. Kiran Kumar
Periodic Jacobi operators naturally arise in numerous applications, forming a cornerstone in various fields. The spectral theory associated with these operators boasts an extensive…
A note on discrete Borg-type theorems
V. B. Kiran Kumar, G. Krishna Kumar
We consider the discrete versions of the well known Borg theorem and use simple linear algebraic techniques to obtain new versions of the discrete Borg type theorems. To be precise…
