Title: Anisotropic inflation with the generalized G-inflation
Abstract:
We give a talk about our ongoing work on anisotropic inflation.
First, we review [1] which proves that homogeneous universes with a positive cosmological constant evolve toward the de Sitter solution.
Next, we show that some classes of the generalized Galileon theories cause anisotropic inflation.
The anisotropic inflation can change the background action dramatically, and we argue its application.
