Dynamics semi-conjugated to a subshift for some polynomial mappings in C2

We study the dynamics near infinity of polynomial mappings f in C-2. We assume that f has indeterminacy points and is non constant on the line at infinity L-infinity. If L-infinity is f-attracting, we decompose the Green current along itineraries defined by the indeterminacy points and their preimages. The symbolic dynamics that arises is a subshift on an infinite alphabet.
