Abstract
In this chapter we begin to study J-Hermitian matrices which most resemble the standard Hermitian ones, and hence have some or all real eigenvalues. The most important property of these eigenvalues is that they remain real under small J-Hermitian perturbations. Sometimes, as in the standard Hermitian case these eigenvalues are expressed by minimax formulae.
