摘要

我们证明了每一个4饱满的剃刀尖的正规Tits四边形X是由一个Witt指数m至少为2的非退化二次空间唯一确定的。若该Witt指数是有限的，则X为标准建筑由相应的B_m或D_m型建筑产生的Tits四边形。

Orthogonal Tits Quadrangles

We show that every 4-plump razor-sharp normal Tits quadrangle X is uniquely determined by a non-degenerate quadratic space whose Witt index m is at least 2. If this Witt index is finite, then X is the Tits quadrangle arising from the corresponding building of type B_m or D_m by a standard construction.
