设q=pn是奇素数p的幂,我们证明了图G的顶点可以划分为t(q)类V(G)=<$t= 1 t(q)Vi,使得任意导出子图<$Vi <$的边数都能被q整除,其中t(q)≤32(q −1)−(2(q−1)−1)124
Let q=pn be a power of an odd prime p. We show that the vertices of every graph G can be partitioned into t(q) classes V(G)=⋃t=1t(q)Vi such that the number of edges in any induced subgraph 〈Vi〉 is divisible by q, where t(q)≤32(q−1)−(2(q−1)−1)124
