초록본문(Abstract) In this talk we discuss a generalization of the classical Tannaka duality to the case of flat schemes over a discrete valuation ring. Developing the work of T. Wedhorn and a result of Saavedra, we provide a categorical condition for a category to be the representation category of a flat affine group scheme over a discrete valuation ring. Some applications to an exact sequence of group scheme homomorphisms and to the fundamental groups schemes are discussed.
