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

Abstract: In this paper, we mainly study an exponential spline function space, construct a basis with local supports, and present the relationship between the function value and the first and the second derivative at the nodes. Using these relations, we construct an exponential spline-based difference scheme for solving a class of boundary value problems of second-order ordinary differential equations (ODEs) and analyze the error and the convergence of this method. The results show that the algorithm is high accurate an… Show more

“…This property of EFup functions of the exponential type gives them an advantage over other finite functions (such as algebraic Fups, splines, wavelets), and it is their flexibility that allows them to “adapt” more to the solution. On a similar track, exponential splines that also contain a tension parameter are used in the literature; these are often applied to solve the singularly perturbed boundary problem [ 58 , 59 ]. When using the exponential type of atomic basis functions, the basic task is to determine the value of the parameter .…”

“…Among the classical numerical methods for solving second-order differential equations, the finite element method (FEM) is presently the most widely used [9]. Nothing better illustrates the challenges of BVP defined by Equation (1) than the fact that, even in recent years, we can find publications where the authors researched methods for solving the non-constant coefficient problem [10][11][12].…”
