Induced Graph Removal Lemma

Statement

A natural generalization of the graph removal lemma is to consider induced subgraphs. In property testing, it is often useful to consider how far a graph is from being induced HH-free. A graph GG is considered to contain an induced subgraph HH if there is an injective map f:V(H)→V(G)f: V(H) \rightarrow V(G) such that (f(u),f(v))(f(u),f(v)) is an edge of GG if and only if (u,v)(u,v) is an edge of HH. Notice that non-edges are considered as well. GG is induced HH-free if there is no induced subgraph GG. We define GG as ϵ\epsilon-far from being induced HH-free if we cannot add or delete ϵn2\epsilon n^2 edges to make GG induced HH-free.
