Abstract: This talk contains two parts. In the first part, I will give a review of various fundamental group schemes from topological fundamental group to fundamental groups schemes over field of arbitrary characteristics, such as Etale fundamental group scheme, Local fundamental group scheme, Nori fundamental group scheme, F-fundamental group scheme and so on. In the second part, I will give a proof of birational invariance of F-fundamental group schemes.
