Methods for the Control of Convergence in Obtained Solutions

  • Kuppalapalle Vajravelu
  • Robert A. van Gorder


The homotopy analysis method of Liao has proven useful in obtaining analytical solutions to various nonlinear differential equations. As discussed in the preceding chapter, in this method, one has great freedom to select auxiliary functions, operators, and parameters in order to ensure the convergence of the approximate solutions and to increase both the rate and region of convergence. In the present chapter, we discuss the selection of the initial approximation, auxiliary linear operator, auxiliary function, and convergence control parameter in the application of the homotopy analysis method, in a fairly general setting.
