WebOct 1, 2013 · 1. Introduction The Rayleigh–Ritz method is a variational method to solve the eigenvalue problem for el-liptic differential operators, that is, to compute their eigenvalues and the correspondingeigenfunctions. It is the direct counterpart of the Ritz method for the solution of the as-signed boundary value problems. WebThe method. The method is widely used in quantum mechanics where the central equation—the time-independent Schrödinger equation—has the form of an eigenvalue equation of an operator commonly denoted by H, the Hamilton (or energy) operator.The operator H is Hermitian and contains second derivatives.
