Abstract
In this paper, on the one hand, the necessary fundamental results of Lie’s theory are presented. Precisely, we expose the notion of infinitesimal generators of a given group action, prologation formula and invariance criterion. On the other hand, some applications of symmetry analysis to some differential equations as construction of similarity solutions, linearization and so on are presentand.
Keywords: Lie group transformations, Differential equation, Similarity solutions..
