چکیده

This paper is concerned with the convergence, global superconvergence, local superconvergence, and stability of collocation methods for u′ t au t bu t . The optimal convergence order and superconvergence order are obtained, and the stability regions for the collocation methods are determined. The conditions that the analytic stability region is contained in the numerical stability region are obtained, and some numerical experiments are given.

Numerical Methods for Boundary Value Problems with Application to Bifurcation Problems

The method of orthogonal collocation for solving boundary value problems in ordinary diierential equation is described, and its relationship to classical nite diierence methods is illustrated. Numerical examples demonstrate the capabilities of software based on orthogonal collocation for analyzing nonlinear diierential equations. A new discretiza-tion method for the solution of elliptic partial...

Solving Parabolic Singularly Perturbed Problems by Collocation Using Tension Splines

Tension spline is a function that, for given partition x0 < x1 < . . . < xn, on each interval [xi, xi+1] satisfies differential equation (D − ρiD)u = 0, where ρi’s are prescribed nonnegative real numbers. In the literature, tension splines are used in collocation methods applied to two-points singularly perturbed boundary value problems with Dirichlet boundary conditions. In this paper, we adap...

Efficient Embedded Formula for Chebyshev Collocation Methods

In this talk, we are concerned with embedded formulae of the Chebyshev collocation methods [1] developed recently. We introduce two Chebyshev collocation methods based on generalized Chebyshev interpolation polynomials [2], which are used to make an automatic integration method. We apply an elegant algorithm of generalized Chebyshev interpolation increasing the node points to make an error esti...

Rapid Convergence of Approximate Solutions for First Order Nonlinear Boundary Value Problems

In this paper we study the convergence of the approximate solutions for the following first order problem u’(t) f(t,u(t));t [O,T],au(O)-bu(to) =c,a,b > 0, a +b > 0,t0 (0,T]. Here fI R tt is such that exists and is a continuous function for some k > 1. Under some additional conditions on -, we prove that it is possible to construct two sequences of approximate solutions converging to a solution ...
