设O是一个完备离散赋值环,其特征p为代数闭剩余域k= O/J(O),对任意a∈ O,我们用a表示a通过约化同态O→ k在k中的象.对于任意的O-代数A,我们分别用A_n和Z(A)表示A的所有可逆元的乘法群和A的中心。在没有歧义的情况下,我们总是用1表示O-代数的单位元。
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.
