Bounds of determinants of matrices satisfying the Hadamard and Brauer conditions.
The authors consider the problem of determination quantitative (lower and upper) bounds on the modulus of the determinant of matrices in the case of the Hadamard or Brauer nonsingularity criteria. It is shown that the established bounds not only refine known bounds but are also sharp in a certain sense.
