In this thesis, we got interested into the Effective Computation of the Topology of Real Algebraic Curves and Surfaces. One can distinguish three main new algorithms in the field of shape representation. Our first algorithm is a certified symbolic-numerical based on sub-resultants properties and computes the topology of a plane algebraic curve with the best known complexity. The second algorithms computes the topology of a space curve defined as the intersection of two implicit algebraic surfaces. For the designing of this algorithm, we introduce the notion of space curve in pseudo-generic position with respect to a given plane. This approach leads to a certified symbolic-numerical algorithm with the best known complexity. The third algorit...
