As far as we are aware, the generalized Sundman transformation has not been applied to a system of equations. The motivation of this work is then to expand the application of the generalized Sundman transformation to a system of ordinary differential equations, in particular, to a system of two second-order ordinary differential equations.

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 outline of the paper is as Some time after, and generalizing this idea, Janin and Bond proposed a new family of time transformations depending on a parameter , called generalized Sundman transformations, given by , where .

Sundman transformation. In [5] it is demonstrated that the solution of the linearization problem via the generalized Sundmantransformation of a second-order ordinary diﬀerential equation given in [4] only gives particular criteria for linearizable equations. The generalized Sundman transformation was also applied in [6,7] for obtaining neces-

The Sundman transformation, whereby a new temporal variable is introduced, results in a system for which solutions exist globally. In addition, it provides a means for simultaneously proving blow-up and ﬁnding analytical estimates of blow-up times. 1. Introduction.

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. p a/µ, s is the eccentric anomaly. •n = 2, c = 1/ p µa(1 − e2

This transformation is a non-point transformation which is defined by the formulae (1) X = F (t, x), dT = G (t, x) dt, (F x G ≠ 0). The linearization problem via the generalized Sundman transformation for second-order ordinary differential equation was investigated in Ref. . 2010-06-15 · 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 Abstract : 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 transformation, a generalized Sundman transformation (Ref. 2), allows one to use any numerical integration method in the independent variable s, which is thus called s-integration.
