An approximation to a sharp type solution of a density-dependent diffusion equation
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 $u_t= [(u+\epsilon u^2)u_x]_x+u(1-u)$ in the case of travelling wave solutions (t.w.s.): $ u(x,t...
