Towards approximation of solitary-wave solutions of non-integrable evolutionary PDEs, via symmetry and qualitative analysis
Abstract:
It is well known that various wave patterns, observed in open dissipative
systems, are described by the non-linear PDE, being not completely integrable.
For this reason their analytical description, generally speaking, is rather
impossible. Yet the information about the existence of the wave patterns
among the solutions with the given symmetry can always be obtained by means
of qualitative theory methods. Such synthetic approach proves to deliver
sufficient information for finding out approximated solitary wave regimes.
We test the effectiveness of this algorithm on the non-linear d'Alembert
equation and the hyperbolic generalization of the Burgers equation.
