题目：Hypergraph Regularity Lemma and its Applications to Tur/'an Problem of Expansions

主讲人：唐与聪

摘要：Hypergraph regularity lemmas, as generalizations of Szemer/'edis regularity lemma for graphs, has proved to be a powerful tool with many subsequent. In this talk, we first introduce the basic versions of hypergraph regularity lemma, dense counting lemma, removal lemma and blow-up lemma; Then we survey results on the Tur/'an problem of uniform hypergraphs and expansions; Finally, we prove an exact Tur/'an number of expanded intersecting cliques by using hypergraph regularity lemma and removal lemma.
