Estimating global subgraph counts by sampling

We give a simple proof of a generalization of an inequality for homomorphism counts by Sidorenko. A special case of our inequality says that if dv denotes the degree of a vertex v in a graph G and hom∆(H, G) denotes the number of homo-morphisms from a connected graph H on h vertices to G which map a...
