A finite difference scheme for the generalized nonlinear Schrodinger equation with variable coefficients is developed. The scheme is shown to satisfy two conser
As we know, a solution of an extremal problem with Hermite interpolation constraints is a system of nodes of corresponding Gaussian Hermite quadrature formula (
In this paper we apply an approach introduced in [6] [7], where continuous norms and hign order estimates and extension are used, to study the convergence of vo
In this contribution we analyse some fundamental features of an iterative method to solve systems of linear equations, following the approach introduced in a pr
It has been observed numerically in [1] that, under certain conditions, all eigenvalues of the first-order Hermite cubic sp]ine collocation differentiation matr
