Variational method in a heterojunction
Physical Review B, 1991Determination des expressions analytiques de l'energie de l'etat fondamental et de la 1ere sous-bande d'une heterojonction en fonction de la temperature et de la concentration en electrons. La difference d'energie E 10 entre la premiere sous-bande et l'etat fondamental est en accord raisonnable avec les donnees obtenues dans une heterojonction GaAs-Ga

Six Variations on the Variational Method
1998As a graduate student in physics at the University of Michigan many years ago I had the good fortune to take a course in function theory from Norman Steenrod that pretty much changed the course of my life. My experience in that course plus several private conversations convinced me to switch out of physics and into mathematics.

On direct methods in the calculus of variations
Computer Methods in Applied Mechanics and Engineering, 1983This review paper surveys the application of the Rayleigh-Ritz method and Galerkin's method to stability problems of structural mechanics. Emphasis is given to a discussion of non-self-adjoint problems where the former method is not applicable.

The Variational and WKB Methods
1994More often than not, it is impossible to find exact solutions to the eigenvalue problem of the Hamiltonian. One then turns to approximation methods, some of which will be described in this and the following chapters. In this section we consider a few examples that illustrate the variational method.

MODIFICATIONS TO THE VARIATE-DIFFERENCE METHOD
Biometrika, 19531-2. The variate-difference method (Anderson, 1914) is closely related to the method of moving averages, and may be regarded as having greater generality. Any moving average difference formula may be shown to be equivalent to an average of higher order differences and, consequently, results obtainable from such formulae may be obtained by ...
