LSD of the Commutator of two data Matrices

Javed Hazarika, Debashis Paul

We study the spectral properties of a class of random matrices of the form $S_{n}^{-} = n^{- 1} (X_{1} X_{2}^{*} - X_{2} X_{1}^{*})$ where $X_{k} = I^£_{k}^{1/2} Z_{k}$ , $Z_{k}$ 's are independent $p\times n…

LSD of sample covariances of superposition of matrices with separable covariance structure

Javed Hazarika, Debashis Paul

We study the asymptotic behavior of the spectra of matrices of the form $S_{n} = \frac{1}{n} X X^{*}$ where $X = \sum_{r = 1}^{K} X_{r}$ , where $X_{r} = A_{r}^{\frac{1}{2}} Z_{r} B_{r}^{\frac{1}{2}}$ , $K \in…

Limiting Spectral Distribution of a Random Commutator Matrix

Javed Hazarika, Debashis Paul

We study the spectral properties of a class of random matrices of the form $S_{n}^{-} = n^{- 1} (X_{1} X_{2}^{*} - X_{2} X_{1}^{*})$ where $X_{k} = I^£^{1/2} Z_{k}$ , for $k = 1, 2$ , $Z_{k}$ 's are independent…
