On Directed Acyclic Exact Extensions
Exact extensions of undirected graphs are well studied, but exact extensions of directed graphs are much less known.We prove that only directe dacyclicgraphor strongly connected graph can be an exact extension. Further more, only transitive tournament can be directed acyclic exact extension.
