差集在乘积构造下的对称差性质

On the Symmetric Difference Property in Difference Sets under Product Construction

Andrew Clickard

摘要:

如果任意三个区组的对称差是一个区组或一个区组的补,则称$(v, k, λ)$对称设计具有对称差性质(SDP)。满足这一性质的对称设计具有最小秩的良好性质,这使得它们的研究很有趣。因此,SDP设计在编码理论应用中变得有用。本文证明了由差集的直积构造而成的差集,其发展具有SDP,也具有SDP。我们还建立了一些结果同构的乘积构造SDP设计。

英文摘要:

A $(v, k, λ)$ symmetric design is said to have the symmetric difference property (SDP) if the symmetric difference of any three blocks is either a block or the complement of a block. Symmetric designs fulfilling this property have the nice property of having minimal rank, which makes them interesting to study. Thus, SDP designs become useful in coding theory applications. We show in this paper that difference sets formed by direct product construction of difference sets whose developments have the SDP also have the SDP. We also establish a few results regarding isomorphisms in product constructed SDP designs.
