Abstract
The dynamics of a thin Huygens front propagating through a turbulent m edium is considered. A rigorous asymptotic expression for the effectiv e velocity v(F) proportional to the front area is derived. The small-s cale fluctuations of the front position are shown to be strongly inter mittent. This intermittency prays a crucial role in establishing a ste ady state magnitude of the front velocity. The results are compared wi th experimental data.
