Abstract:

The speaker will give a brief introduction on string landscape inflation and multi-stream inflation. Several existing ways of phenomenologically generating random potential will also be presented. She will then talk about how they generate the random potential in their work. The results about constraints caused by bifurcation in parameter space in inflation in a landscape will be discussed. It is found that, for example, in 10 dimensions, only 10³~10⁶ of the parameter space volume leads to unique classical trajectories.
