... subgraph of H has at least |S  |−1leaves. Now, we can quickly complete the proof of the main theorem using the result about the special graph Λ proven in the next section. Proof of Theorem 4. ... Consider a copy of H in G. It contains at least one of the components of order m, thus it has at least two vertices of the same color. Therefore there is no rainbow induc...
