Exponential spline solutions for a class of two point boundary value problems over a semi-infinite range

Abstract

In this paper, we developed numerical methods of order O h 2 and O h 4 based on exponential spline function for the numerical solution of class of two point boundary value problems over a Semi-infinite range. The present approach gives better approximations over all the existing finite difference methods. Properties of the infinite linear system are established. Convergence analysis and a bound on the approximate solution are discussed. Test problem with various kinds of boundary conditions is included to illustrate the practical usefulness and superiority of our methods.Keywords Exponential spline · Two-point boundary value problem over semi-infinite range · Monotone matrices · Convergence analysis

An Exponential Spline Difference Scheme for Solving a Class of Boundary Value Problems of Second-Order Ordinary Differential Equations

“…In recent years, with the deepening of research, people have begun to use nonpolynomial splines to solve such problems. Zahra [6], Rao and Kumar [7], Tirmizi et al [8], Ramadan et al [9], Surla and Stojanović [10], Jha [11,12], and Kadalbajoo and Patidar [13] have carried out a lot of research in this area and achieved very high computational accuracy.…”

CUBIC SPLINE SOLUTION OF FRACTIONAL BAGLEY-TORVIK EQUATION Vol. 1(2) July 2013, No. 10, pp. 230-241 W. K. ZAHRA AND S. M. ELKHOLY

“…The main objective of this work is to use cubic polynomial spline function to establish a new numerical method for the FBVP (1-2). This approach has its own advantage that it not only provides continuous approximations to y(x) , but also y (j) (x); j = 1; 2 for at every point of the range of integration ([25], [30]- [32]). This paper is organized as follows: In section 2, we introduce some de…nitions and theorem necessary to our work.…”

An efficient method for solving multi-point boundary value problems and applications in physics

“…Saadatmandi and Dehghan (2011) proposed the sinc-collocation technique for finding the numerical solution of multi-point boundary value problems. Also the interested reader is referred to Caglar et al (2006), Fang et al (2002), Ha and Lee (2002), Ha (2001), Inc and Evans (2003), Jang (2008), Mohsen and El-Gamel (2008), Taiwo (2002), and Zahra (2009) for some published research on two-point boundary value problems.…”
