设k是特征不同于2的完美域。证明了运动稳定同伦范畴中球谱的切片滤波在Grothendieck-Witt群GW(K)上的滤子是I-进滤子,其中I是GW(K)中的增广理想.
Let k be a perfect field of characteristic different from two. We show that the filtration on the Grothendieck-Witt group GW(k) induced by the slice filtration for the sphere spectrum in the motivic stable homotopy category is the I-adic filtration, where I is the augmentation ideal in GW(k).
