We prove that every connected graph on n vertices can be covered by at most nΓ2+O(n 3Γ4 ) paths. This implies that a weak version of a well-known conjecture of Gallai is asymptotically true.
## Abstract We show that all graphs with a simple extension property are projective. As a consequence of this result we settle in the affirmative a conjecture of Larose and Tardif and characterize all homogeneous graphs which are projective. Β© 2004 Wiley Periodicals, Inc. J Graph Theory 47: 81β86,
