RESUMO

The study of the stability of L4 point of in the photogravitational problem is accomplished. Firstly a normalization algorithm for 2 and 3 degree freedom is accomplished. The equations of motion are written in an extended canonical and then, using the Hori-Lie, method put in a normal form. The stability of the system is analyzed by the theorem of Kovalev and Savechenko be applied to the photogravitational restricted three body problem.
