Let ck,j(n) be the number of (k,j)-colored partitions of n. Recently, Keith proved that for j{4,7}, if c9,j(3ln+2)0(mod27) for all n0, then l is large. We prove that such l do not exist. Furthermore, for any positive integers a,b with (a,b)=1, there exist infinitely many positive integers n such that c9,j(an+b)0(mod27), where j{4,7}.

关于受限k色分区的问题

C,j(n) 是数量 (,j)-彩色分区 n. 最近,Keith 证明了对于j{4,7}, 如果 C9,j(3n+2)0(模组27) 对所有人 n0, 然后 很大。我们证明这样的不存在。此外,对于任何正整数一种,(一种,)=1,存在无穷多个正整数 n 以至于 C9,j(一种n+)0(模组27), 在哪里 j{4,7}.
