EPS_LREP#
A structured Linear Response eigenvalue problem.
Note#
The problem is formulated as \(Hx=\lambda x\), where \(H\) has the form
\[\begin{split}H_1 = \begin{bmatrix}
A & B \\
-B & -A
\end{bmatrix},\end{split}\]
where \(A\) and \(B\) are real symmetric. An alternative form is
\[\begin{split}H_2 = \begin{bmatrix}
0 & K \\
M & 0
\end{bmatrix},\end{split}\]
where \(K=A-B\) and \(M=A+B\).
