✦ Synopsis


We prove that every connected graph on n vertices can be covered by at most nΓ‚2+O(n 3Γ‚4 ) paths. This implies that a weak version of a well-known conjecture of Gallai is asymptotically true.

Let H=(V H , E H ) be a graph, and let k be a positive integer. A graph G=(V G , E G ) is H-coverable with overlap k if there is a covering of the edges of G by copies of H such that no edge of G is covered more than k times. Denote by overlap(H, G) the minimum k for which G is H-coverable with over

## Abstract An (__n, q__) graph has __n__ labeled points, __q__ edges, and no loops or multiple edges. The number of connected (__n, q__) graphs is __f(n, q)__. Cayley proved that __f(n, n__^‐1^) = __n__^nβˆ’2^ and Renyi found a formula for __f(n, n)__. Here I develop two methods to calculate the exp

## Abstract An edge of a 3‐connected graph is said to be __contractible__ if its contraction results in a 3‐connected graph. In this paper, a covering of contractible edges is studied. We give an alternative proof to the result of Ota and Saito (__Scientia__ (A) 2 (1988) 101–105) that the set of co
