Abstract
Denote byH n the set ofn byn, positive definite hermitian matrices. Hadamard proved thath(A)≧det(A) for allA∈H n, whereh(A) is the product of the main diagonal elements ofA. Subsequently, M. Marcus showed that per(A)≧h(A) for allA∈H n. This article contains a result for all generalized matrix functions from which it follows thath(A)≧(per(A1/n))n,A∈H n.
