强正则构型

Strongly regular configurations

Marién Abreu, Martin Funk, Vedran Krčadinac, Domenico Labbate

AI总结:

本文研究点图与线图均强正则的组合构型,构造新例、建立存在条件、给出点数不超过200的可行参数表,并证明部分可行构型不存在。

摘要:

我们研究其关联点图与线图均为强正则图的组合构型。文中构造了不属于已知类别(如偏几何及其推广,或椭圆半平面)的例子。证明了必要的存在条件,并给出了至多含200个点的此类构型可行参数表。还证明了某些具有可行参数的构型不存在。

英文摘要:

We study combinatorial configurations with the associated point and line graphs being strongly regular. Examples not belonging to known classes such as partial geometries and their generalizations or elliptic semiplanes are constructed. Necessary existence conditions are proved and a table of feasible parameters of such configurations with at most 200 points is presented. Non-existence of some configurations with feasible parameters is proved.
