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. which is a non-point transformation is called a generalized Sundman transformation (GST). The requisite form of a linearizable ordinary differential Equation (2.1) that can be translated into a linear ordinary differential equation.

Sundman transformation

Authors of [6] also discovered the Sundman sym-metry. Detailed analysis of Sundman symmetries is given by Euler and Euler [8]. Some 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. 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.

In addition, it provides a means for simultaneously proving blow-up and ﬁnding analytical estimates of blow-up times.

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. Furthermore, using the modified correct, but at the turn of the century the Finnish mathematician K, Sundman.
