DESCRIPTION:Title: <a href="https://researchseminars.org/talk/EPC/76/">Hyp
 ergraphs with minimum positive uniform Turán density</a>\nby Ander Lamais
 on (Masaryk University) as part of Extremal and probabilistic combinatoric
 s webinar\n\n\nAbstract\nReiher\, Rödl and Schacht showed that the unifor
 m Turán density of every 3-uniform hypergraph is either 0 or at least 1/2
 7\, and asked whether there exist 3-uniform hypergraphs with uniform Turá
 n density equal or arbitrarily close to 1/27. We construct 3-uniform hyper
 graphs with uniform Turán density equal to 1/27. This is based on joint w
 ork with Frederik Garbe and Daniel Kráľ.\n
