At first impression --- this looks a very interesting site, well worth a visit.
well ..... Someone wanted to know when there are pairs of complex roots for a real polynomial. Someone else offered that it can't depend on the coefficients because they can be made arbitrtarily small and so are useless !!!!! I don't have a reference in mind, but that question was solved 500 years ago, give or take a century or two. Sturm sequences, alternation of signs, whatever ... . They want problems. Maybe someone could offer them the zeta function. That reputation bit --- you get points for answering questions, it seems. Karma, in other words. -hvm ------------------------------------------------- www.correo.unam.mx UNAMonos Comunicándonos
