摘要翻译:
我们计算了任意正则基X上(分裂的)Grassmann簇的全Witt群。答案是X的全Witt环上的一个自由模。我们为这个自由模提供了一个明确的基础,这个自由模由一类特殊的年轻图索引,我们称之为偶年轻图。

英文摘要:
We compute the total Witt groups of (split) Grassmann varieties, over any regular base X. The answer is a free module over the total Witt ring of X. We provide an explicit basis for this free module, which is indexed by a special class of Young diagrams, that we call even Young diagrams.
