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