SOLITARY WAVES, PERIODIC PEAKONS AND COMPACTONS ON FOLIATIONS IN A HERTZ CHAIN MODEL

For a Hertz chain model, by using the methodology of dynamical systems and singular traveling wave theory developed by Li and Chen [9] to its traveling wave system defined on a two-dimensional foliations in the three-dimensional space, under different parameter conditions, the existence of all possible bounded solutions (solitary wave solutions, periodic wave solutions, periodic peakons, and compactons) is proved. For the nonlinearity exponent k = 3/2 , k = 2 and k = 3 in the model, as many as 23 exact explicit parametric representations of the above-mentioned traveling wave system are obtained.
