Hello all,
Is there a command in maxima to do the following kind of
simplification on a sum?
1) sum(x[m],m,0,s)-sum(x[m+1],m,0,s) -> x[s+1]
2) sum(x[i+m,j],m,0,s)-sum(x[i+m+1,j],m,0,s) -> x[i+s+1, j] (if I'm not wrong)
3) sum(sum(x[i+m,j+n],n,0,s),m,0,s)-sum(sum(x[i+1+m,j+n],n,0,s),m,0,s)
-> sum(x[i,j+n],n,0,s)-sum(x[i+s+1,j+n],n,0,s) (if I'm not wrong)
I'm particularly interested by 2) and 3) :)
Thanks in advance for any help!
