Abstract
Having introduced main notions of the geometry based on an indefinite scalar product we will now study special classes of matrices intimately connected with this scalar product. These will be the analogs of the usual Hermitian and unitary matrices. At first sight the formal analogy seems complete but the indefiniteness of the underlying scalar product often leads to big, sometimes surprising, differences.
