Abstract:

A class of secondorder linear ordinary differential equation with twopoint boundary value problem was transfered into absolute value equation via  finite difference method, and an iterative method was proposed, then the convergence analysis was given. Numerical experiments show that this method has the advantages of less number of iterations and high precision.

Key words: secondorder linear ordinary differential equation, twopoint boundary value problem, finite difference method, absolute value equation, iterative method
