Abstract

In this paper a Sinc-Galerkin method incorporated with the double exponential transformation (abbreviated as the DE transformation) for the two-point boundary value problem of fourth-order ordinary differential equation is considered. In this method the error bound O(exp(-c^'N/logN))(c^'0) is attained as in the Sinc-collocation method based on the DE transformation where N is a parameter representing the number of terms in the Sinc approximation. High efficiency of the Sinc-Galerkin method with the DE transformation is confirmed by some numerical examples and the numerical results were compared with ones obtained by Sinc-collocation method based on the DE transformation.
