Computation of eigenpair partial derivatives by Rayleigh–Ritz procedure

open access: yesJournal of Computational and Applied Mathematics, 2012
The author considers the computation of partial derivatives of eigenvalues and eigenvectors of a matrix dependent on several parameters. The well-known Rayleigh-Ritz procedure of a matrix is extended to a matrix-valued function. The new method computes the eigenpairs and their partial derivatives simultaneously.

Rayleigh-Ritz variational method in the complex plane

open access: yesPhysica Scripta
Abstract We present a systematic study of the Rayleigh–Ritz variational method for quantum oscillators in the Segal–Bargmann space. We rigorously derive the normalizability condition
