| Abstract: |
| We address the question of the large-time behavior of solutions of reaction-diffusion equations in periodic media. We will start with the description of the asymptotic shape of the invasion set, which is characterized by the Freidlin-Gartner formula. We will then present some recent results for the bistable equation, obtained in collaboration with H. Guo and F. Hamel, about a regular version of the Freidlin-Gartner formula, as well as the convergence of the profile of the solution towards pulsating traveling fronts. |
