Alspach conjectured that every connected Cayley graph on a finite Abelian group A is Hamilton-decomposable. Liu has shown that for |A| even, if S = {s 1 ,. .. , s k } ⊂ A is an inverse-free strongly minimal generating set of A, then the Cayley graph Cay(A; S), is decomposable into k Hamilton cycles, where S denotes the inverse-closure of S. Extending these… (More)

In the context of list-coloring the vertices of a graph, Hall's condition is a generalization of Hall's Marriage Theorem and is necessary (but not sufficient) for a graph to admit a proper list-coloring. The graph G with list assignment L satisfies Hall's condition if for each subgraph H of G, the inequality |V (H)| σ∈C α(H(σ, L)) is satisfied, where C is… (More)
