Description (last modified by )
sage: var("j,p", domain="integer") (j, p) sage: X=function("X")
Compare :
sage: foo=sum(X(j),j,1,p);foo sum(X(j), j, 1, p) sage: bar=maxima("sum(X(j),j,1,p)").sage();bar sum(X(j), j, 1, p) sage: bool(foo==bar) True
with
sage: gee=X(j).maxima_methods().sum(j,1,p);gee p*X(j) ## Nonsense... sage: bool(foo==gee) False
The problem also exists with products, see #17502 and #17505.
