On the invariant soliton-like solutions of a non-integrable evolutionary system
Abstract:
We considered a modeling system, describing long nonlinear waves propagation
in a medium, possessing an internal structure on mesoscale, and manifesting
non-local features. The system occurs to be similar to some Hamiltonian
system, but does no coincide with it for any physically justified values
of the parameters. However a system of ODE's, obtained from the initial
one via the self-similarity reduction occurs to be Hamiltonian. Using this
fact, we show that the factorized system possesses a one-parameter family
of homoclinic regimes, corresponding to soliton-like traveling wave solutions
of the initial system.
