Abstract
We present a review of our recent works directed towards
discovery of a periodic, kinklike and solitonlike travelling
wave solutions within the models of transport phenomena and the
mathematical biology. Analytical description of these wave
patterns is carried out by means of our modification of the
direct algebraic balance method. In the case when the analytical
description fails, we propose to approximate invariant travelling
wave solutions by means of an infinite series of exponential
functions. The effectiveness of the method of approximation is
demonstrated on a hyperbolic modification of Burgers equation.
Key words:
generalized Burgers equation; telegraph equation; model of somitogenesis; direct algebraic balance method; periodic and solutionlike travelling wave solutions; approximation of the solitonlike solutions.
