 Author Comment/Response Bill Simpson 02/27/13 01:15am Here is an example kappa In[1]:= kappa[t_,lambda_]:=lambda^2+t+1; Reduce[kappa[t,lambda]==0,lambda] Out[2]= lambda== -Sqrt[-1-t] || lambda==Sqrt[-1-t] For different definitions of kappa the form of the result may be very different. Thus providing a single simple method of negating that solution seems risky. Manually I can say that your solution would be lambda!= -Sqrt[-1-t] && lambda!=Sqrt[-1-t] is the set of lambda where there are no zeros. Without knowing more about your kappa I don't see a way to say any more than this. URL: ,
