| Feb 5, 2017 at 9:09 | comment | added | Pietro Majer | I guess dividing by ${ {\alpha+\beta\over\beta} l \choose l}$ both sides in the first identity should give a Vandermonde's identity en.wikipedia.org/wiki/Vandermonde%27s_identity | |
| Feb 5, 2017 at 8:32 | comment | added | Pietro Majer | In the RHS of the first identity, do you have $\alpha kl $ or rather $\beta kl$? I would expect something depending only on ${\alpha+\beta\over\beta}$, not on $\alpha$ or $\beta$, since so is the LHS. | |
