Jun 20, 2010 at 15:24 comment added Olivier Many thanks for your kind answers. I now understand that the question is too broad, and its solutions are far beyond my skills. I will work at narrowing my question, and come back here if I cannot find a solution by myself. Tnaks again, Olivier
Jun 18, 2010 at 20:22 comment added Dan Piponi It makes a big difference whether the coefficients are arbitrary approximately known reals, or simple constants that are known exactly. If you give more detail on this, and the type of polynomials, this might possibly turn into an MO question that gets modded up.
Jun 18, 2010 at 17:58 comment added S. Carnahan I second Steve Huntsman's book recommendation. I'm afraid the question as it stands is a bit broad for MathOverflow - since the set of roots forms a complex hypersurface, it is difficult to algorithmically "find" all of them, except by descriptive means (e.g., using the polynomial itself, or computing interesting invariants of the zero set).
Jun 18, 2010 at 17:42 comment added Steve Huntsman ...If you truly need to learn about this stuff in any generality at all, a good way to start would be (to first acquaint yourself with the basic notions of abstract algebra like [groups], rings, fields, and ideals and then) check out this book: books.google.com/books?id=7eLkq0wQytAC
Jun 18, 2010 at 17:40 comment added Steve Huntsman The study zeros of polynomials is a vast and sophisticated subject called algebraic geometry. Usually the set of zeros is a curve or surface of some sort, called a variety (en.wikipedia.org/wiki/Algebraic_variety). One of the basic insights of algebraic geometry is that varieties correspond to algebraic objects called ideals (see the same wiki page). In practice these algebraic objects are what is used to perform computations on varieties...
