关于Haar酉矩阵的部分转置
On the Partial Transpose of a Haar Unitary Matrix
摘要:
本文研究了部分转置对Haar分布随机酉矩阵的极限$*$ -分布的影响。如果我们固定,$b$,块的数量,我们表明,部分转置可以分解成一个和的$b$矩阵是渐近自由和同分布。然后,我们考虑不同的块分解的联合效果,并表明在一些温和的假设下,我们也得到渐近自由。
英文摘要:
We consider the effect of a partial transpose on the limit $*$-distribution of a Haar distributed random unitary matrix. If we fix, $b$, the number of blocks, we show that the partial transpose can be decomposed into a sum of $b$ matrices which are asymptotically free and identically distributed. We then consider the joint effect of different block decompositions and show that under some mild assumptions we also get asymptotic freeness.
