Discrete-Time Orthogonal Spline Collocation Methods For Schrödinger Equations In Two Space Variables

, 1994
. Two discrete-time orthogonal spline collocation schemes are formulated and analyzed for solving the linear time-dependent Schrodinger equation in two space variables. These are CrankNicolson and alternating direction implicit (ADI) schemes employing C

Decoupled Smooth Interfaces for Spectral-Element Approximations of Parabolic or Elliptic Type

, 2007
A method is examined to approximate the interface conditions for Chebyshev polynomial approximations to the solutions of parabolic problems, and a smoothing technique is used to calculate the interface conditions for a domain decomposition method.

Single Step Smooth Interface for Parabolic Spectral Elements

, 2007
A method is examined to calculate a smooth interface for spectral elements. The idea of the method is to find a polynomial of one less degree that interpolates the interior and one side of a subdomain.

Some unconditionally stable time stepping methods for the 3-D Maxwell's equations

, 2003
Almost all the di#culties that arise in the numerical solution of Maxwell's equations are due to material interfaces. In case that their geometrical features are much smaller than a typical wave length, one would like to use small space steps with ...

Orthogonal Spline Collocation Methods For Schrödinger-Type Equations In One Space Variable

, 1994
. We examine the use of orthogonal spline collocation for the semi-discretization of the cubic Schrodinger equation and the two-dimensional parabolic equation of Tappert.
