On the positive definiteness of a matrix. I

1991
Let \(A\) be an \(n\times n\) complex positive semi-definite matrix. The author gives some equivalent conditions for \(A\) to be positive semi- definite and obtains a relation between complex positive definite matrices and stable matrices. Moreover, complex generalized positive definite matrices are also discussed.
