平衡加权矩阵

Balanced Weighing Matrices

Hadi Kharaghani, Thomas Pender, Sho Suda

摘要:

本文给出了构造加权矩阵和某些对称设计的统一方法。假设加权矩阵$W(n,p)$中的权重$p$是素数幂,则表明对于每个正整数$m$都存在一个$$W\left(\frac{p^{m+1}-1}{p-1}(n-1)+1,p^{m+1}\right)$$。$n=p+1$的情形归结为具有经典参数的平衡权矩阵$$W\left(\frac{p^{m+2}-1}{p-1},p^{m+1}\right).$$。详细讨论了它与某些结合方案的等价性。

英文摘要:

A unified approach to the construction of weighing matrices and certain symmetric designs is presented. Assuming the weight $p$ in a weighing matrix $W(n,p)$ is a prime power, it is shown that there is a $$W\left(\frac{p^{m+1}-1}{p-1}(n-1)+1,p^{m+1}\right)$$ for each positive integer $m$. The case of $n=p+1$ reduces to the balanced weighing matrices with classical parameters $$W\left(\frac{p^{m+2}-1}{p-1},p^{m+1}\right).$$ The equivalence with certain classes of association schemes is discussed in details.
