Generalized Galilean Genesis |
|
Abstract |
Galilean Genesis is one of the alternative inflation models and originally constructed from the Galileon theory.This model has an interesting feature that our universe started from the Minkowski universe. We generalized Galilean Genesis models by using Horndeski theory. We studied the evolution of background and perturbations. We find this model solve the problems that inflation model solved in the same way. We can make a flat power spectrum of scalar perturbation by choosing the specific value of introduced parameter in this model. I will talk above and recent results. |
