Given Hermitian matricesand, and, we characterize under which conditions there exists a matrixwithsuch that the non-Hermitian block-matrix\begin {equation*}{\left [\begin {array}{cc}{A} & {-AK}\\{K^* A} & {D}\end {array}\right]}\end {equation*} has a positive (semi) definite Schur complement with respect to its submatrix. Additionally, we show thatcan be chosen such that diagonalizability of the block-matrix is guaranteed and we compute its spectrum. Moreover, we show a connection to the recently developed frame theory for Krein spaces. References
