Thomas,
In[1]:=
Sum[F[x],{x,-a,a}]==Sum[F[y],{y,-a,a}]
Out[1]=
Sum[F[x], {x, -a, a}] == Sum[F[y], {y, -a, a}]
Mathematica stops at the syntactical level.
We need to buid in some way of making the syntactical forms to sam
In[15]:=
%/.x|y->xy
Out[15]=
True
But we need to avoid variabel clashes and deal with depndencies amongst
the summation variables.
