(Eingegsngen am 30. 13. 1980) .ibstract. We consider the set of noiilioniogeneous MARKOV fields on T = N o r T =Z with finite .Itate spaces E,, nET, with fixed local characteristics. For T = N we show that has at most iV-=lim inf lEnl phases. If T=Z, has a t most N-, . N-phases, wIiereN-,=linl inflEnl. We give examples, t h a t for T = N for any number i'c, 1 s k a N -, there are local characteristics with k phase8, whereas for I ' = Z every number I k, 1 s Z S N -~, 1 S k S Xoccurs. We describe the inner structure of q, the behaviour a t infinity and the connection between the one-sided and the twosided tail-fields. Simple examples of Markov fields which are no MARKOV processes are given.
