WebSzemerédi's Regularity Lemma proved to be a powerful tool in the area of extremal graph theory. Many of its applications are based on its accompanying Counting Lemma: If G is an ℓ‐partite graph with V (G ) = V 1 ∪ … ∪ V ℓ and ∣︁V i ∣︁ = n for all i ∈ [ℓ], and all pairs (V i , V j ) are ε‐regular of density d for 1 ≤ i ≤ j ≤ ℓ and ε ≪ d , then G contains ... Web3 Burnside’s Lemma For a nite group G that acts on set X, let X=G be the set of orbits of X. Then, Burnside’s Lemma states that jX=Gj= 1 jGj X g2G jXgj In De nition 3, we de ned jXgjabove to be the subset of X that is xed by g. This also means the the number of orbits is equal to the average number of xed points of G. Proof of Burnside’s ...

WebTheorem 1.2 (Graph Removal Lemma). For every graph Hand ">0, there exists a constant = (H;") >0 such that any n-vertex graph with less then njV (H)j copies of H can be made H-free by deleting at most "n2 edges. The proof is similar to the triangle removal lemma (one can use the graph counting lemma to prove the graph removal lemma).
