Please, could someone explain the discrepancy between these two results : Solve[ { u + m/x^2 v, v + m/x^2 u } == 0, {y,z} ] => {} Solve[ { u + 1/x^2 v, v + m/x^2 u } == 0, {y,z} ] => {{}} The math meaning is not significant (these are simplified from the actual case),but in a larger program I do Length[ result[[1]] ], and it objects to the first instance (which I think is incorrect). Thanks. Mike Burns Rowland Institute
