Title: Planar fronts in bistable coupled map lattices

Abstract: Planar fronts in multidimensional coupled map lattices can be studied
by reduction to an one-dimensional extended dynamical system that
generalises one-dimensional coupled map lattices. This methodology is
fully investigated and developed. Continuity of fronts velocity with
the coupling strength and with the propagation direction is proven.
Examples are provided and illustrated by some numerical pictures.
