We prove that every -vertex 4-uniform hypergraph with minimum codegree at least has a spanning tight component. This is tight, and it settles the 4-uniform…

Kühn and Osthus conjectured in 2013 that regular tripartite tournaments are decomposable into Hamilton cycles. Somewhat surprisingly, Granet gave a simple counterexample to this c…
