Abstract
G. Ringel conjectured that for every positive integer n other than 2, 4, 5, 8, 9, and 16, there exists a nonseparable graph with n cycles. It is proved here that the conjecture is true even with the restriction to planar and hamiltonian graphs.

The number of nonseparable graphs on n labeled points and q lines is u(n, 9). In the second paper of this series an exact formula for u(n, n + k) was found for general n and successive (small) k. The method would give an asymptotic approximation for fixed k as n + 30. Here an asymptotic approximatio
## Abstract Suppose __r__ ≥ 2 is a real number. A proper __r__‐flow of a directed multi‐graph $\vec {G}=(V, E)$ is a mapping $f: E \to R$ such that (i) for every edge $e \in E$, $1 \leq |f(e)| \leq r-1$; (ii) for every vertex ${v} \in V$, $\sum \_{e \in E^{+(v)}}f(e) - \sum \_{e \in E^{-(v)}}f(e) =
We propose a conjecture: for each integer k ≥ 2, there exists N (k) such that if G is a graph of order n ≥ N (k) and d(x) + d(y) ≥ n + 2k -2 for each pair of nonadjacent vertices x and y of G, then for any k independent edges e 1 , . . . , e k of G, there exist If this conjecture is true, the condi
We prove that every bipartite C 2' -free graph G contains a C 4free subgraph H with e(H) ! e(G)=(' À 1). The factor 1=(' À 1) is best possible. This implies that ex(n; C 2' ) 2(' À 1)ex(n; fC 4 ; C 2' g), which settles a special case of a conjecture of Erdo ˝s and Simonovits.
## Abstract We consider finite, undirected, and simple graphs __G__ of order __n__(__G__) and minimum degree δ(__G__). The connectivity κ(__G__) for a connected graph __G__ is defined as the minimum cardinality over all vertex‐cuts. If κ(__G__) < δ(__G__), then Topp and Volkmann 7 showed in 1993 f
