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.

SLOCC Invariants for Multipartite Mixed States
Naihuan Jing, Ming Li, Xianqing Li-Jost, Ting-Gui Zhang and Shao-Ming Fei
Abstract
We construct a nontrivial set of invariants for any multipartite mixed states under the SLOCC symmetry. These invariants are given by hyperdeterminants and independent from basis change. In particular, a family of $d^2$ invariants for arbitrary $d$-dimensional even partite mixed states are explicitly given.
