我们研究了类型为$ ilde{W}=(idotimesvarphi)W$的随机矩阵,其中$W$是参数$(dn,dm)$的复Wishart矩阵,$varphi:M_n(mathbb C) o M_n(mathbb C)$是一个自伴随线性映射。我们证明,在适当的假设下,我们有$d 0 $特征值分布公式$ δ m ilde{W}simpi_{mn ho} ×次
We study the random matrices of type $ ilde{W}=(idotimesvarphi)W$, where $W$ is a complex Wishart matrix of parameters $(dn,dm)$, and $varphi:M_n(mathbb C) o M_n(mathbb C)$ is a self-adjoint linear map. We prove that, under suitable assumptions, we have the $d oinfty$ eigenvalue distribution formula $delta m ilde{W}simpi_{mn ho}oxtimes u$, where $ ho$ is the law of $varphi$, viewed as a square matrix, $pi$ is the free Poisson law, $ u$ is the law of $D=varphi(1)$, and $delta=tr(D)$.
