A combinatorial interpretation of the bijection of Goulden and Yong
We define a dual of a graph, generalizing the definition of Goulden et al. (2002), which only applies to trees; then we reprove their main result using our new definition. We in fact give two characterizations of the dual: a graph-theoretic one and an algebraic one, showing that they are in fact the...
