Abstract:Let µ I denote the minimal number of generators of an ideal I of a local ring R M . The Dilworth number d R = max µ I I an ideal of R and Sperner number sp R = max µ M i i ≥ 0 are determined in the case that R = A G , where G = Z/pZ k is an elementary abelian p-group, A zA is a principal local ring with A/zA of characteristic p > 0, and z n = 0 for small values of n.
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.
