Extremal Numbers for 2 to 1 Directed Hypergraphs with Two Edges Part II: The Degenerate Cases
Alex Cameron
Let a 2 to 1 directed hypergraph be a 3-uniform hypergraph where every edge has two tail vertices and one head vertex. For any such directed hypergraph F let the nth extremal numbe…

Extremal Numbers for 2 to 1 Directed Hypergraphs with Two Edges Part I: The Nondegenerate Cases
Alex Cameron
Let a 2 to 1 directed hypergraph be a 3-uniform hypergraph where every edge has two tail vertices and one head vertex. For any such directed hypergraph F let the nth extremal numbe…

Extremal Problems on Generalized Directed Hypergraphs
Alex Cameron
In this paper we define a class of combinatorial structures the instances of which can each be thought of as a model of directed hypergraphs in some way. Each of these models is un…
