Duality theories for p-primary etale cohomology III

Abstract

This paper is Part III of the series of work by the first named author on duality theories for p-primary etale cohomology, whose Parts I and II were published in 1986 and 1987, respectively. In this Part III, we study a duality for p-primary etale nearby cycles on smooth schemes over henselian discrete valuation rings of mixed characteristic (0, p) whose residue field is not necessarily perfect.
