Abstract:
We investigate the behavior of positive solutions to the Cauchy problem of logarithmic diffusion equation with non-symmetric flux boundary condition at space infinity. We show that extinction of the solution occurs in a finite time and a re-scaled solution converges to the traveling wave. Our results also include some log-concavity properties of solutions.
