Problems for which solutions develop finite-time In the literature, the generalized Sundman transformation has been used for obtaining necessary and sufficient conditions for a single second- and third-order ordinary differential equation to be equivalent to a linear equation in the Laguerre form. As far as we are aware, the generalized Sundman transformation has not been applied to a system of pdf) aas 18-467 a piecewise-constant sundman transformation sigma10-051. 222KB Jun 04 2011 12:10:40 AM A Note on the Use of Generalized Sundman Anomalies in the 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 comparable.

The result transformed the above equation into  Sundman solved this problem for the case of n = 3 with non-zero angular By means of this transformation, a complete answer is given for the global solution  We show that the equation can be linearized by means of a nonlocal transformation, the so-called Sundman transformation.

•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 A Sundman transformation is a reparametrization of the temporal variable that was first used as part of an analytic solution to the three-body problem.

Closely related to the concept of a generalized Sundman transformation is the notion of an associated Sundman symmetry. This is similar in spirit to the existence of a Lie symmetry under point transformations. Suppose that we have a generalized Sundman transformation (GST) X (T) = F (t

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 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 . This family includes the most common anomalies for appropriate values of and , the mean anomaly for , , the eccentric anomaly for , the true anomaly for , , and the Nacozy intermediate anomaly for and [ 4 ]. 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.

The necessary and sufficient conditions which allow the nonlinear fifth-order ordinary differential equation to be transformed to the simplest linear equation are found.
