Abstract

In this series of talks, we study the p-primary sheaves, so-called logarithmic de Rham-Witt sheaves, on a variety of characteristic p. In the first talk, we give an overview of different constructions of de Rham-Witt complexes. Then we investigate the basic properties of these p-primary sheaves, such as purity, duality results, in the second talk. The last two talks are focused on generalizations and applications, especially generalize these to regular case and apply to cohomological Hasse principles.
