具有大禁止子图的图的个数

The number of graphs with large forbidden subgraphs

Bela Bollobas, Vladimir Nikiforov

摘要:

本文推广了Erdos,Frankl,Rodl,Alexeev,Bollobas和Mesason的一些结果,渐近地确定了不含某些大子图的图的个数.特别地,如果H_1,.,H_n,.是具有色数r_1,.,r_n,.和o(logn)阶的条件下,渐近地确定了不含H_n的n阶图的个数.对于诱导子图也给出了类似的结果。

英文摘要:

In this note, extending some results of Erdos, Frankl, Rodl, Alexeev, Bollobas and Thomason we determine asymptotically the number of graphs which do not contain certain large subgraphs. In particular, if H_1,...,H_n,... are graphs with chromatic numbers r_1,...,r_n,... and order o(log n), we dermine asymptotically the number of graphs of order n not containing H_n as a subgraph. We also give similar results for induced subgraphs.
