Research output: Contribution to journalArticlepeer-review


A graph drawn in the plane with n vertices is -fan-crossing free for geqslant if there are no edges,e1,…,ek, such that ldots …,ek have a common endpoint and crosses all We prove a tight bound of on the maximum number of edges of a -fan-crossing free graph, and a tight bound for a straight-edge drawing. For geqslant we prove an upper bound of (k-1)(n-2) edges. We also discuss generalizations to monotone graph properties.
