张量空间中锥的可分解性

The Decomposable Projective Cone in Tensor Vector Space

在文献 [1 ]的基础上研究张量空间中锥的性质 ,得到了张量空间中射影锥的极端向量的表示形式 .给出了张量空间中射影锥可分解的充分必要条件 ,并由此可得出有限维实空间中真正锥可分解的已有结论 .

We studied the properties of the projective cone in tensor vector space defined by Barker. We obtained the expressions for the projective cone and the extreme vectors in the projective cone. We gave the sufficient and necessary condition of decomposable for the projective cone.
