Dynamics of Bianchi I cosmologies in exp(λR) gravity

We investigate the cosmological dynamics of homogeneous and anisotropic Bianchi I geometries in exp(λR) gravity. We find the exact solutions and study the behavior and stability of these solutions for both vacuum and matter cases. It is found that stable solutions exist corresponding to accelerated expansion at late times, which can describe the inflation era of the universe. Solutions also exist corresponding to decelerated expansion, which can describe structure formation of the universe. (author)
