In this note, we wilt show the following three theorems. Here F denotes an arbitrary field, F* the multiplicative group of F, and F [~, 3-1] the ring of Laurent polynomials in~ with coefficients in F. Let W (F) be the Witt ring over F with the maximal ideal I (F) consisting of classes with even rank (cf.[, 11]). Then there are two exact sequences as follows (cf. Suslin [-20]):
