论文摘要
在本文中,我们研究了PG中的正交Buekenhout-Metz Unital U的脚的几何结构(2,Q^2)。我们表明,每个点的脚形成一组类型(0,1,2,4)。此外,我们讨论了任何四个塞子的结构,并确切确定脚何时形成弧线。
In this article we look at the geometric structure of the feet of an orthogonal Buekenhout-Metz unital U in PG(2,q^2). We show that the feet of each point form a set of type (0,1,2,4). Further, we discuss the structure of any 4-secants, and determine exactly when the feet form an arc.
