Abstract
For a double array of random variables \(\{X_{m,n},\,m\geq 1,n\geq 1\}\) such that for any \(k\geq 1,\) \(\ell\geq 1\), the collection \(\{X_{i,j},2^{k-1}\leq i<2^{k},2^{\ell-1}\leq i<2^{\ell}\}\) is \(M\)-pairwise negatively dependent, conditions are provided under which \(\max\limits_{k\leq m,\,\ell\leq n}\left|\sum_{i=1}^{k}\sum_{j=1}^{\ell}X_{i,j}\right|/(a_{m}b_{n})\to 0\) almost surely as \(\max(m,\,n)\to\infty\), where \(\{a_{n},\,n\geq 1\}\) and \(\{b_{n},\,n\geq 1\}\) are two sequences of positive constants. The sharpness of the result is illustrated by an example.
