Hi.
I need to work with the following kinds of products of sums;
sum[i1,{i,1,n}]*sum[i2,{i2,i1,n}]*sum[i3,{i3,i2,n}]*...*sum[iN,{iN,i(N-1),n}]
I need to do this in complete generality, so I want to find a way of imputing it into mathematica without having to type out the case for each n,N.
I tried
product[sum[ij,{ij,i(j-1),n}],{j,1,N}]; j0:=1
but it gives the wrong answer.
any suggestions?
cheers!
