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 ...

Analytic Continuation via Hadamard’s Product

SIAM Journal on Mathematical Analysis, 1978
This paper presents an operational procedure derived from Hadamard’s convolution product which is used to construct continuations of analytic functions in the form of integral functional representations. These representations are more useful in the study of analytic properties than the underlying Taylor’s series, and the method extends the previously ...

A Note on the Hadamard Product

Canadian Mathematical Bulletin, 1959
Let A = (aij), B = (bjj), be two n-square matrices over the complex numbers. Then the n-square matrix H = (hjj) = ij(aijb) is called the Hadamard product of A and B, H = AoB, [l; p. 174]. Let the n2 - square matrix K = A⊗B denote the Kronecker product of A and B.
