Abstract

This research considers an application of the generalized Sundman transformation, i.e.,
               gif.latex?u(t)&space;=&space;f(x,y)
               gif.latex?dt&space;=&space;g(x,y)dx
to the linearization problem of third-order ordinary differential equations. Complete necessary and sufficient conditions for third-order ordinary differential equations to be linearizable into the general form of a linear third-order ordinary differential equation
               gif.latex?u'''&space;+&space;\beta&space;u''&space;+&space;\alpha&space;u'&space;=\gamma&space;u&space;=&space;\eta
where gif.latex?\beta,gif.latex?\alpha,gif.latex?\gamma and gif.latex?\eta are constants, are obtained for the case gif.latex?f_{x} = 0.
