Abstract
The property of a Hermitian n × n matrix A that all its principal minors of order n − 1 vanish is shown to be a purely algebraic implication of the fact that the lowest two coefficients of its characteristic polynomial are zero. To prove this assertion, no information on the rank or eigenvalues of A is required.
