Adelic Eisenstein Classes and Applications to Stickelberger Elements

Abstract: We construct an adelic refinement of Nori’s Eisenstein cohomology classes and their integral version due to Beilinson, Kings, and Levin. This adelic perspective provides a natural and unified framework for studying integrality properties of partial zeta values and leads to new divisibility results for Stickelberger elements. This was joint work with Michael Spiess.
