广义循环密度与可分性的一个充分条件
Generalized Circulant Densities and a Sufficient Condition for Separability
摘要：
在一系列文件与Kossakowski，第一作者研究了性质的密度，其中正部分transpositrionm（PPT）性质可以很容易地检查。Baumgartner、Hiesmayr和Narnhofer也从不同的角度研究了这些密度。在本文中，我们将展示如何支持这样的密度可以表示在有限几何中的线，以及如何相同的结构本身检查必要的PPT条件和一个新的充分条件的可分性。
英文摘要：
In a series of papers with Kossakowski, the first author has examined properties of densities for which the positive partial transpositrionm (PPT) property can be readily checked. These densities were also investigated from a different perspective by Baumgartner, Hiesmayr and Narnhofer. In this paper we show how the support of such densities can be expressed in terms of lines in a finite geometry and how that same structure lends itself to checking the necessary PPT condition and to a novel sufficient condition for separability.
