仿射空间中的区传递设计

Block-Transitive Designs in Affine Spaces

Michael Huber

摘要:

本文研究了大$t$在仿射空间中的区传递$t$-$(v,k,λ)$设计,重点讨论了重要指标$λ=1$的情形.我们证明了不存在允许仿射型自同构块-传递群的非平凡5- $(v,k,1)$设计。此外,我们证明了相应的不存在性结果保持4- $(v,k,1)$设计,除了可能当群是一维仿射。我们的方法涉及到有限的2-齐次仿射置换群的考虑。

英文摘要:

This paper deals with block-transitive $t$-$(v,k,λ)$ designs in affine spaces for large $t$, with a focus on the important index $λ=1$ case. We prove that there are no non-trivial 5-$(v,k,1)$ designs admitting a block-transitive group of automorphisms that is of affine type. Moreover, we show that the corresponding non-existence result holds for 4-$(v,k,1)$ designs, except possibly when the group is one-dimensional affine. Our approach involves a consideration of the finite 2-homogeneous affine permutation groups.
