Intersection representation of digraphs in trees with few leaves
In-Jen Lin, Malay K. Sen, Douglas B. West
Abstract
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.
