Talk	Oral abstract	Title	Homogenous Solutions of Effective Gravity
Co-authors	Juliano A. de Deus
Abstract	According to quantum field theory in curved space, the one loop corections to the effective action introduce quadratic terms in the curvature. We present classical homogenous solutions of this effective gravity of the Bianchi type I and VII_A. These geometries are the anisotropic generalizations of the Friedmann open, Hˆ3, and Einstein de Sitter R^3 solutions, respectively. Isotropisation will be discussed.
