Complex Algebraic Curves,mplex plane ?. (with coordinates . and .) of dimension two, since the real dimension of a 2-dimensional complex plane is equal to 4, and equating to zero the complex number . (.,.) means equating to zero both its real part and its imaginary part; that is, we have two equations in the four real variables (Re ., Im., Re., Im.).

Introduction,This book is concerned with one of themost fundamental questions ofmathematics: the relationship between algebraic formulas and geometric images.

Projective Geometry,It is clear to everyone that the branches of a hyperbola “go off to infinity,” but these words acquire a precise meaning only in projective geometry, the science that arose in the mathematical examination of rails “converging” a long way off as they go straight to the horizon.
