Finite propagation and saturation in reaction-diffusion-advection equations governed by p-Laplacian operator

The paper concerns front propagation for the following mono-stable reaction-diffusion-advection equation $$f(u)u_x + g(u)u_\tau = [d(u)|u_x|^{p-2} u_x]_x+ \rho(u), \quad (x,\tau)\in \R\times [0,+\infty).$$ Besides existence and non-existence results for traveling wave solutions, the main focus is their classification: we provide criteria to establish if they attain one or both the equilibria at a finite time and in this case, if they are continuable as $C^1$-solutions or if they are sharp solutions.
