Abstract
In this paper, some estimations of bounds for determinant of Hadamard product of H-matrices are given. The main result is the following if A=(aij) and B=(bij) are nonsingular H-matrices of order n and ∏ni=1aiibii＞0, and Ak and Bk,k=1,2,⋯,n, are the k×k leading principal submatrices of A and B, respectively, then
where M(Ak) denotes the comparison matrix of Ak.
