Yes, they should be included. The trick is to use the conditions such that the series break down early. We have something like ##f'+g''=0## and if the variables are separated, we can simply integrate.I was looking for separated solutions too, just in the form of a product instead of a sum (no joy). But wouldn't such a possibility (sum) be included in my power series solution though? I used double power series thinking that the only restriction I imposed was that I wouldn't be able to identify solutions not having a power series expansion
