We consider the initial-value problem for the radially symmetric nonlinear Schrödin-ger equation with cubic nonlinearity (NLS) in d = 2 and 3 space dimensions. To approximate smooth solutions of this problem, we construct and analyze a numerical method based on a standard Galerkin finite element spatial discretization with piecewise linear, continuous(More)
The purpose of this paper is to describe a package of transportable FORTRAN programs which may be used to implement decision trees or flowcharts on a digital computer. The package is called NITPACK and it consists of two primary subroutines NITREE and NIT. The purpose of NITREE is to convert a decision tree or flowcharts into a format that may be(More)
