On the halphen transform of algebraic space curves
Alfrederic Josse, Françoise Pène
The Halphen transform of a plane curve is the curve obtained by intersecting the tangent lines of the curve with the corresponding polar lines with respect to some conic. This tran…

Degree and class of caustics by reflection for a generic source
Alfrederic Josse, Francoise Pene
We are interested in the study of caustics by reflection of irreducible algebraic planar curves (in the complex projective plane). We prove the birationality of the caustic map (fo…

On the class of caustics by reflection
Alfrederic Josse, Francoise Pene
Given any light position S in the complex projective plane P^2 and any algebraic curve C of P^2 (with any kind of singularities), we consider the incident lines coming from S (i.e.…
