“…Then the value of the function ( , ) at the moment of breaking can be calculated by formula (31) provided by (41), (42), and (47): The plot of points of breaking br and br , normalized to the value of the amplitude and value of the amplitude multiplied wave number , respectively, depending on the values of the quantity is shown in Figure 3. Temporal evolution of the transverse perturbations ( , ), normalized to the amplitude of the initial perturbation, calculated by formulas (18), (20), (22), and (31) for the harmonic initial perturbation with the values = 0.1, = 1, and = 10, is represented in Figure 4. From Figure 4 it is seen that with the propagation of the harmonic perturbation the wave profile becomes asymmetric and the asymmetry for the functions ( ) and ( ) is shown differently.…”
