计数子结构III:四重系统
Counting substructures III: quadruple systems
摘要:
对于各种四重系统F,我们给出了具有给定顶点数和边数的四重系统F的拷贝数的渐近尖锐的下界。我们的结果扩展了Furedi,Keevash,Pikhurko,Simonovits和Sudakov谁证明在相同的条件下,有一个副本的$F$。我们的证明使用超图移除引理和稳定性结果相应的Turan问题证明了上述作者。
英文摘要:
For various quadruple systems F, we give asymptotically sharp lower bounds on the number of copies of F in a quadruple system with a prescribed number of vertices and edges. Our results extend those of Furedi, Keevash, Pikhurko, Simonovits and Sudakov who proved under the same conditions that there is one copy of $F$. Our proofs use the hypergraph removal Lemma and stability results for the corresponding Turan problem proved by the above authors.
