On tame Nori fundamental group: There are multiple notions of tameness of a cover of normal projective varieties over a field of positive characteristics in higher dimensions which were studied by M. Kerz and A. Schmidt. These notions allow us to define tame Nori fundamental group scheme of a quasi projective variety. The theory of parabolic bundles provide another approach. I will discuss these definitions and relations between them. I will also talk about a Lefschetz type theorem for this fundamental group. This is based on a joint work with Indranil Biswas and AJ Parameswaran.
