The *-invariance and the conformal invariance of the equations are mentioned. It is also proved that all non-linear solutions have zero invariants: F_{μν}F^{μν} = (*F)_{μν}F^{μν} = 0. The three invariant characteristics of the non-linear solutions: amplitude, phase and scale factor are introdiced and discussed.14 pages, LaTex, no figuresPattern Formation and SolitonsHigh Energy Physics - TheoryQuantum Physicstext
