Let T be a tree such that there is a proper n-coloring c of the vertices of T which, besides a technical condition, is a k b k a k -free, i.e., T contains no subdivision of a path u 1 , . . . , Then T has O(kn) vertices. (The technical condition requires that T contains no subdivision of a properly
We consider extremal problems 'of Tur~ type' for r-uniform ordered hypergraphs, where multiple oriented edges are permitted up to multiplicity q. With any such '(r, q)-graph' G" we associate an r-linear form whose maximum over the standard (n -1)-simplex in R" is called the (graph-) density g(G ") o
