Description: A family of nonlinear transformation groups of Hermitian matrices preserving the basic linear congruences properties is constructed. Each group generates a structure of a partially ordered vector multispace on the set of Hermitian matrices. Determinant inequalities which allow as to find geodesic lines for an analog of indefinite metric on positive definite matrix set are obtained.
