In this paper, we demonstrate that the solution of the linearization problem via the genera-lized Sundman transformation of second-order ordinary differential equations given in [4] only gives particular criteria for linearizable equations.

Ehsan Taheri The Emden differential equation is one of the most widely studied and challenging nonlinear dynamics equations in literature. It finds applications in various areas of study such as celestial mechanics, fluid mechanics, Steller structure, isothermal gas spheres, thermionic currents and so on. Because of the importance of the equation, the method of generalized Sundman transformation (GST) as 400 N Euler and M Euler for a given Fand Gthat achieves this linearisation. We named the transformation (1.2)-(1.3) the Sundman symmetry [5] of linearisable third-order equations. generalized Sundman transformation method and obtain its general solution. Again we show that the extended equation of (1.1) via the Riccati transformation is simpler in form in comparison to the extended equation in [7], and can readily be linearizable by the Sundman transformation to obtain the general solution.

The authors of [7] obtained that any second-order linearizable ordinary differential equation which can be mapped into the equation X′′ = 0 via a generalized limearizing transformation has to be of the form x′′ +A 3(t,x)x′3 +A2(t,x)x

Sundman introduced the generalized Sundman transformations in 1992. Later on Duarte et al. [ 20 ] applied this method to transform second-order ordinary differential equations into free particle equations. Transformations used for solving a linearization problem are point transformations, contact transformations, generalized Sundman transformations, and tangent transformations. The generalized Sundman transformation was considered earlier for second-order ordinary differential equations by Duarte et al. (1994) using the Laguerre form.

Introduction The main aim of this paper is to build up a set of semi-analytical integrators based on the use of a class of anomalies defined by means of a generalized Sundman transformation. The integrators are based on the developments of the mean anomaly and the vector radius according to the new anomaly. To manipulate these developments, a Poisson series processor called poison.h has been used. The linearization problem of a second-order ordinary differential equation by the generalized Sundman transformation was considered earlier by Duarte, Moreira and Santos using the 2010-10-12 A new approach using the generalized Sundman transformation to solve explicitly and exactly in a straightforward manner the cubic elliptic Duffing equation is proposed in this study. The method has the advantage to closely relate this equation to the linear harmonic oscillator equation and to be applied to solve other nonlinear differential equations.

A generalized Sundman transformation dt crnds for exponent n 1 may be used to accelerate the numerical computation of high-eccentricity orbits, by transforming time t to a new independent variable s. Once transformed, the integration in uniform steps of s effectively gives analytic step variation in t with larger time steps at apogee than at perigee, making errors at each point roughly
