We show that conjectures of Thomassen (every 4-connected line graph is hamiltonian) and Fleischner (every cyclically 4-edge-connected cubic graph has either a 3-edge-coloring or a dominating cycle) are equivalent.

β¦ Synopsis
Let G be a bridgeless cubic graph. Fulkerson conjectured that there exist six 1-factors of G such that each edge of G is contained in exactly two of them. Berge conjectured that the edge-set of G can be covered with at most five 1-factors. We prove that the two conjectures are equivalent.

The 3-flow conjecture of Tutte is that every bridgeless graph without a 3-edge cut has a nowhere-zero 3-flow. We show that it suffices to prove this conjecture for 5-edge-connected graphs.
## Abstract Counterexamples are presented to the following two conjectures of Hilton: A graph which does not contain a spanning __K__~1t~ is Vlβcritical if and only if it is VCβcritical. If __G__ is a classβtwo graph which contains a spanning Plβcritical subgraph __H__ of the same chromatic index
## Abstract Berge's elegant dipath partition conjecture from 1982 states that in a dipath partition __P__ of the vertex set of a digraph minimizing , there exists a collection __C__^__k__^ of __k__ disjoint independent sets, where each dipath __P__β__P__ meets exactly min{|__P__|, __k__} of the ind
## Abstract We show that the Axiom of Choice is equivalent to each of the following statements: (i) A product of closures of subsets of topological spaces is equal to the closure of their product (in the product topology); (ii) A product of complete uniform spaces is complete.
