Abstract:
A natural covering responsible for the complexity of the ramification of roots of the general real polynomial equation is considered, and the homology groups of its base are calculated; for equations of degree ⩽5, a complete description of the topology of this base is given.
Keywords:
ramification, discriminant, real algebraic function, Schwarz genus.
