Abstract
In the first part of the talk we will consider real planar rational curves of degree 4. We will prove that the rigid isotopy classification of real rational curves of degree 4 in the projective plane can be solved by considering their chord diagrams. In the second part of the talk, we will consider real rational knots on the 3-sphere. The 3-sphere can be realized as a subvariety of the projective space of dimension 4. Real rational knots in the 3-sphere are curves in the 4-dimensional projective space that lie on the 3-sphere. We will prove a rigid isotopy classification of all real rational knots of degrees 6. We will also prove methods of constructing examples of real rational knots of a given degree. The rigid isotopy classification of real rational knots in the projective space is known up to degree 5. We will partially extend this result by classifying real rational knots of degree 6 with four double points, in the projective space. | 56 pages
