Abstract
The thermo-diffusive model for flame propagation, with high activation energies and Lewis number close to one is considered. It has been sho wn by Sivashinsky, by means of formal arguments, that the plane wave s olutions were stable above a certain critical value of the Lewis numbe r, and then bifurcated into two-dimensional waves. A rigorous proof of this fact, as well as the stability of the two-dimensional waves, sti ll remained open problems; we provide here an answer to these two ques tions.
