Polynomial equation solving by lifting procedures for ramified fibers

Let be given a parametric polynomial equation system which represents a generically unramified family of zero-dimensional algebraic varieties. We exhibit an efficient algorithm which computes a complete description of the solution set of an arbitrary parameter instance from a complete description of...
