In the paper, the structure of the O_K[G]-module F(m_M) is described, where M/L, L/K, and K/ℚ_p are finite Galois extensions (p is a fixed prime number), G = Gal(M/L), m_M is a maximal ideal of the ring of integers O_M, and F is a Lubin–Tate formal group law over the ring O_K for a fixed uniformizer π.
