Abstract

Abstract

In this paper we are interested in the large time behavior of the nonlinear diffusion equation u₁=(φ(u))_xx+φ(u), (x∈R, f∈R+=(0,+∞)) We consider functions φ(u) and φ(u) which allow the equation to possess traveling wave solutions. We first present an existence and uniqueness as well as some comparison principle result of generalized solutions to the Cauchy problem. Then we give for some threshold results, from which we can see that u=a is stable, while u=0 or u=1 is unstable under some assumptions, etc.
