Such transformations provide an intriguing perspective on the two-body problem for any spherically symmetric potential. Generalized Sundman Transformation •Sundman (1912) developed a time transformation to attempt to solve the three body problem, dt = crds, where c is a 2 body constant. •This regularizes and linearizes the equations of motions. •Generalized form: •n = 1, c = dt = crnds.

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. 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 In order to derive a method to obtain lineari- zing generalized Sundman transformations (1.4) of a given S-linearizable equation (1.3), Muriel and Romero [13] found additional relationships between the functions φ and ψ in (1.4) and the functions F (x, y), F1 (x, y) and F2 (x, y), in (1.3), and used these to provide constructive methods to derive the linearizing S-transformations for the The Sundman transformation can also be used on non-Hamiltonian systems while the Poincar¶e transformation can be used, in some cases, with more e–cient symplectic integrators.

## GENERALIZED SUNDMAN TRANSFORMATIONS Transformation equation Sundman (Ref. 3) and Levi-Civita (Ref. 4), in attempting to solve the restricted problem of three bodies, introduced the transformation of the independent variable dt = crds, (1) with c constant for the two-body orbit, because this transformation regularizes, and in fact linearizes,

We use a particular substitution to transform the equation into a linearizable second order non-linear form and then we determine 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 Laguerre form. The results obtained in the present paper demonstrate that their solution of the linearization problem for a second-order ordinary differential equation via the generalized Sundman transformation is Sundman transformation, three-body problem.
