    "abstract": "In this Letter we suggest a method of convex rigid frames in the studies of\nthe multipartite quNit pure-states. We illustrate what are the convex rigid\nframes and what is the method of convex rigid frames. As the applications we\nuse this method to solve some basic problems and give some new results (three\ntheorems): The problem of the partial separability of the multipartite quNit\npure-states and its geometric explanation; The problem of the classification of\nthe multipartite quNit pure-states, and give a perfect explanation of the local\nunitary transformations; Thirdly, we discuss the invariants of classes and give\na possible physical explanation.",
