Do you mean to say that you have complex numbers p_j and your inequalities are of the form |p_j-p_k|<=C and |p_j-p_k|>=D, and that you also have some equations on Re(p_j) and Im(p_j) ? (as the subject talks about inequalities, but here you talk about equations, I assume you can have both, no?) > Would you know of any way to solve this type of equations, or to > ensure that no solution exists ? > > Thank youuuuuuuu ! :-) > > Nathann > > -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
