在这篇文章中,通过多次求导从德格鲁格平面构造出了各种各样的奇阶平移平面,并证明了它们承认范形。例如,我们证明了通过替换绝大多数不相交网络得到的奇阶次正则平面承认fano构型。进一步地,对于奇数且大于1,任何有序的子正则平面都可以嵌入到包含原平面作为子平面并且允许Fano配置的有序的子正则平面中。
In this article a wide variety of odd-order translation planes, constructedfrom Desarguesian planes by multiple derivation, are shown to admit Fanoconfigurations. For example, we show that subregular planes of odd order obtained by the replacement of at most disjoint nets admitFano configurations. Further, for odd and greater than 1, any subregularplane of order can be embedded into a subregular plane of order that contains the original plane as a subplane and admits Fano configurations.
