So these expressions cannot really be handled anyway and simplification is unnlikely to do something useful. Better simplify in fricas. Considering memory errors from large simplification tasks: yes, simplification (particularly full simplification) can involve some algorithms with very high time and space complexities, so seeing memory errors is not surprising by itself. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
