# PEP_HYPERBOLIC

A quadratic eigenvalue problem with hyperbolic structure.

## Note

This is reserved for the case of a quadratic eigenvalue problem \((K+\lambda C+\lambda^2M)x=0\) with Hermitian coefficient matrices, and in addition \(M\) is positive definite and \((x^*Cx)^2>4(x^*Mx)(x^*Kx)\) for all nonzero \(x\in\mathbb{C}^n\). All eigenvalues are real, and form two separate groups of \(n\) eigenvalues, each of them having linearly independent eigenvectors.
