Emphasis Period Seminar: "Counting Curves with Tangency Conditions: A comparison of approaches"

| Abstract: | How many plane conics through four general points are tangent to a general line? Relative Gromov-Witten theory is devoted to "virtually" answering questions of this nature. Chuck Cadman proposed an alternative approach through orbifold Gromov-Witten theory of r-th root orbifolds. I'll report on joint work with Cadman and Jonathan Wise, where we "virtually" compare the two approaches when counting genus 0 curves. |
