Abstract :

Lie symmetry group method is applied to study the Barlett and Whitaker’s equations. The symmetry group and its optimal system are given,and group invariant solutions associated to the symmetries are obtained. Finally the structure of the Lie algebra symmetries is determined.

Keywords :

Lie group analysis, Symmetry group, Optimal system, Invariant solution.
