Allan K. Steel, Computing with algebraically closed fields, Journal of Symbolic Computation, Volume 45, Issue 3, March 2010, Pages 342-372, ISSN 0747-7171, http://dx.doi.org/10.1016/j.jsc.2009.09.005. would really be much better. It would avoid any number field computations. If an embedding in CC or RR is required, it could be tracked with just numerical information. One would use finite fields to track identity. If there's such a use for QQbar, it might be interesting to run a project in that direction. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
