Title: Integral models for unipotent completion

Abstract: For a given group, unipotent completion yields a unipotent algebraic group defined over a field of characteristic zero which best approximates it. We will introduce some integral models of such a unipotent group when the field is complete with respect to a discrete valuation. The speaker's motivation is to formulate Iwasawa theoretic questions for unipotent groups of arithmetic origin.
