Semicircle Law for Hadamard Products

SIAM Journal on Matrix Analysis and Applications, 2007
Summary: Assuming \(p/n\rightarrow 0\) as \(n\rightarrow\infty\), we will prove the weak and strong convergence to the semicircle law of the empirical spectral distribution of the Hadamard product of a normalized sample covariance matrix and a sparsing matrix, which is of the form \(A_p=\frac{1}{\sqrt{np}}(X_{m,n}X_{m,n}^*-\sigma^2nI_m)\circ D_{m ...
