A Laplace decomposition algorithm applied to a class of nonlinear differential equations. (English) Zbl 0996.65068
Using Laplace transform, the author constructs recursively an approximate solution of an initial value problem of the nonlinear differential equation $$y''+ a(x)y'+ b(x) y= f(y),$$ where the nonlinear term $f(y)$ is decomposed in terms of Adomian polynomials [see {\it G. Adomian}, Solving frontier problems of physics: The decomposition method, Kluwer, Dordrecht (1994; Zbl 0802.65122)]. But the convergence of this method is not considered. Some numerical examples are given, where higher iterates of the approximate solution are computed by a computer algebra system.
