An Extension of Franklin’s Bijection

2001
We are dealing here with the power series expansion of the product . This expansion may be readily obtained from an identity of Sylvester and the latter, in turn, may be given a relatively simple combinatorial proof. Nevertheless, the problem remains to give a combinatorial explanation for the massive cancellations which produce the final result.
