Query: Intersection representation of digraphs in trees with few leaves   The leafage of a digraph is the minimum number of leaves in a host tree in
which it has a subtree intersection representation. We discuss bounds on the
leafage in terms of other parameters (including Ferrers dimension), obtaining a
string of sharp inequalities.
