    "abstract": "We propose a more general method for detecting a set of entanglement\nmeasures, i.e. negativities, in an \\emph{arbitrary} tripartite quantum state by\nlocal operations and classical communication. To accomplish the detection task\nusing this method, three observers, Alice, Bob and Charlie, do not need to\nperform the partial transposition maps by the structural physical\napproximation; instead, they are only required to collectively measure some\nfunctions via three local networks supplemented by a classical communication.\nWith these functions, they are able to determine the set of negativities\nrelated to the tripartite quantum state.",
