Let O be a complete discrete valuation ring with an algebraically closed residue field k= O/J (O) of characteristic p. For any a∈ O, we denote by a the image of a in k through the reduction homomorphism O→ k. For any O-algebra A, we denote by A∗ and Z (A) the multiplicative group of all invertible elements of A and the center of A, respectively. Without ambiguity, we will always denote by 1 the identity element of an O-algebra.
