Multigraphs without large bonds are wqo by contraction

Abstract : We show that the class of multigraphs with at most p connected components and bonds of size at most k is well-quasi-ordered by edge contraction for all positive integers p, k. (A bond is a minimal non-empty edge cut.) We also characterize canonical antichains for this relation and show that they are fundamental.
