Mechanism of the appearance of the cellular structure of a shock wave in the region of its ambiguous representation

The mechanism of the formation of the cellular structure for a planar shock wave in an equilibrium medium, which arises due to its ambiguous representation characterized by the fulfillment of the condition $L>1+2M$, i.e., one of the linear criteria of the instability of the shock wave in media with arbitrary thermodynamic properties, has been considered. It has been shown that this process is based on “switching” between different types of the possible decay configurations, which occurs during the motion and interaction of the transverse waves moving along the shock wave front.
