广义四边形的覆盖

Covers of generalized quadrangles

Joseph A. Thas, Koen Thas

摘要:

本文解决了Cardinali和Sastry [2]提出的关于有限经典广义四边形的$2$-覆盖的因式分解问题。为此,我们发展了广义四边形覆盖因式分解的一般理论,特别是我们研究了此类覆盖和相关几何的同构问题。作为一个副产品,我们得到了新的结果,半部分几何来自$θ$-覆盖,并考虑相关问题。

英文摘要:

We solve a problem posed by Cardinali and Sastry [2] about factorization of $2$-covers of finite classical generalized quadrangles. To that end, we develop a general theory of cover factorization for generalized quadrangles, and in particular we study the isomorphism problem for such covers and associated geometries. As a byproduct, we obtain new results about semipartial geometries coming from $θ$-covers, and consider related problems.
