I think the problem is more involved. Of course, 1/(x+y) does not have a power series expansion. Switching to a "multivariate Laurentseries" is a bit harder than one might expect. http://www.risc.jku.at/publications/download/risc_4600/main.pdf Ralf -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
