报告摘要：
Graph homomorphism orders are the partial order on graphs (cores) induced by the existence of graph homomorphism. In this talk we will give an overview on the results on graph homomorphism orders, specially the duality, density and universality of graph homomorphism orders, some of the results can be used to give the corresponding results on other homomorphism orders, like injective/surjective homomorphisms and locally injective/surjective/bijective homomorphisms.
