“…1.1 Review of necessary results of [5] Let us consider the Picard group of the integer group ring ZC 2 . The first observation is that P ic(ZC 2 ) ∼ = P ic(A), where A can be presented as a Cartesian product of Z[ Here P ic, the Picard group, is the same as the projective class group or simply the class group for Dedekind rings.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
