【 摘 要 】

Let K be a field of characteristic 2. We give natural presentations of the subgroups I-n(K) of the Witt ring W(K) of K and the subgroups I-n W-q (K) of the Witt group Wq(K) of K. Our results generalize the results of Arason and Elman in [J.K. Arason, R. Elman, Powers of the fundamental ideal in the Witt ring, J. Algebra 239 (2001) 150-160], where the characteristic is assumed to be different from 2. (c) 2007 Elsevier Inc. All rights reserved.
