Sánchez-Garduño, F. and Maini, P. K. (1994) An approximation to a sharp type solution of a density-dependent diffusion equation. Applied Mathematics Letters, 7 (1). pp. 47-51.
In this paper, we use a perturbation method to obtain an approximation to a saddle-saddle heteroclinic trajectory of an autonomous system of ordinary differential equations (ODEs) arising in the equation in the case of travelling wave solutions (t.w.s.): . We compare the approximate form of the solution profile and speed thus obtained with the actual solution of the full model and the calculated speed, respectively.
