稀疏随机图中子图计数的模统计

Modular statistics for subgraph counts in sparse random graphs

Bobby DeMarco, Jeff Kahn, Amanda Redlich

摘要:

讨论了Kolaitis和Kopparty的一个问题,证明了对于给定的整数$q>1$和两两非同构连通图$G_1...G_k$,如果$p=p(n) $使得$\Pr(G_{n,p}\supseteq G_i)\to 1$ $\forall i$,则当$ξ_i$为$G_{n,p}$中$G_i$的拷贝数时,$(ξ_1...ξ_k)$在${\bf Z}_q^k$上渐近均匀分布.

英文摘要:

Answering a question of Kolaitis and Kopparty, we show that, for given integer $q>1$ and pairwise nonisomorphic connected graphs $G_1...G_k$, if $p=p(n) $ is such that $\Pr(G_{n,p}\supseteq G_i)\to 1$ $\forall i$, then, with $ξ_i$ the number of copies of $G_i$ in $G_{n,p}$, $(ξ_1...ξ_k)$ is asymptotically uniformly distributed on ${\bf Z}_q^k$.
