【 摘 要 】

In this article, we review our recent works on fourth order Weyl gravity, and try to obtain same results for cosmological coefficients, using a different approach. Indeed we shall impose a de Sitter like condition on the original components of field equations. Afterwards using the reduced equations on a definite geometric background, we derive the same results as in [1], for same cosmological constraints.
