AbstractIt is proved that the range of the negative signature of the hermitian completions of the partial matrix ABB∗CDD∗E is an interval, and explicit formulae for the bounds of this interval are obtained. As an application the solvability of the problem of lifting with prescribed negative signature of defect is settled
