Dear Richy and Alexei, Many thanks for the commments, I will try to implement them. Meanwhile, here is another small proposition: to allow GiNaC the rewriting rule of exponents: (x^c1)^c2 -> x^(c1 * c2) for the additional case of c1=-1 and c2>0. It was explicitly forbidden in exam_powerlaws.cpp, but it seems to be a rudiment of old times, when GiNaC was not aware of positiveness. I am including the respective patch. Best wishes, Vladimir -- Vladimir V.
