We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Detection of Genuine Multipartite Entanglement in Multipartite Systems
Jing-Yun Zhao, Hui Zhao, Naihuan Jing and Shao-Ming Fei
Abstract
We investigate genuine multipartite entanglement in general multipartite systems. Based on the norms of the correlation tensors of a multipartite state under various partitions, we present an analytical sufficient criterion for detecting the genuine four-partite entanglement. We show that our criterion can detect genuine entanglement by detailed example. The results are generalized to arbitrary multipartite systems.
