Invariants of Curves in RP2 and R2
Student-Run Geometry/Topology Seminar| Speaker: | Ekaterina Fuchs, UCD |

I will be speaking about Abby's Paper "Invariants of Curves in RP2 and R2". There is an elegant relation among the double tangent lines, crossings, inflection points, and cusps of a singular curve in the plane. We give a new generalization to singular curves in RP. We note that the quantities in the formula are naturally dual to each other in RP2 and we give a new dual formula. This paper is something of a sequel to the talk I gave last time I spoke in the seminar.
