Straight line representation of planar linear hypergraphs (Solved)
Conjecture Every planar linear hypergraph has a straight line representation in the plane which maps each vertex to a point and each edge to a straight line segment , in such a way that:
- \item for each vertex and each edge , we have: \item for each couple of distinct edges , we have
