Lutz filtration as a Galois module



In the paper, we consider a formal module F(M L ) and its Lutz filtration M L M L 2 M L 3 ⊃..., where K is a finite extension of the field of p-adic numbers Q p , L/K is a normal extension without higher ramification with Galois group G = Gal(L/K), F(X, Y) is a formal group over a ring of integers O K with finite height. We study its structure as Z[G]-modules. The main result is contained in Theorem 4.
