Try domain:complex before calling integrate; that changes the result to what I think is expected. I guess (emphasis on guess) that the problem originates not from gamma_incomplete itself but from terms of the form (-1)^(1/n) which are the result of simplifying or evaluating gamma_incomplete. Sorry I can't be more helpful. best, Robert Dodier -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
