Maple verifies it for k from 1 to 100 with arbitrary D. Perhaps someone who knows WZ theory <http://en.wikipedia.org/wiki/WZ_theory> can prove it. On Wed, Aug 20, 2014 at 10:55 PM, Warren D Smith <warren.wds@gmail.com> wrote:
sum( (D+k-j)! / (k-j)! * (-1)^j * (2*k+1+D-2*j)^(2*k+1) / (j! * (2*k+1+D-j)!), j, 0, k ) = 4^k
claims lots of checking. (only checked when D>0 is integer.)
But... how to prove it?
