Some applications of the discrete fourier transform to problems of crystal lattice deformation II
TL;DR: In this article, the theory of the discrete Fourier transform is applied in solving a system of difference equations describing the positions of atoms in a deformed crystal lattice, which is approximated by the Born-Karman model modified to include the internal energy of the undeformed crystal.
Journal ArticleDOI
Overimplicit multistep methods
TL;DR: In this paper, a new class of methods called overimplicit multistep methods is introduced for numerical solution of ordinary differential equations by a new set of methods, called over-implicit multi-step methods.
Journal ArticleDOI
Approximate solution of an inhomogeneous abstract differential equation
TL;DR: In this article, the necessary and sufficient conditions under which a rational function approximates the semigroup of operators exp(tA) generated by an infinitesimal operator A were developed.
