On the deduction of a non linear perturbation equation used to solve the galaxy formation problem

الملخص EN

In this paper a nonlinear equation for solving the galaxy formation problem is deduced, by applying the coordinate condition on the Generalized Held Equations (GFE).

This nonlinear equation in the limit of weak field is found reducible to the linear equation of General Relativity (GR) used to solve the galaxy formation problem.
