If you have a question about this talk, please contact Andrea Brini. Enumerative geometry deals with the study of counting problems in geometric spaces. Example questions are: “How many conics are there through 5 points in the plane?” “How many lines are there on a cubic surface?” “How many curves are there on a quintic threefold?” A powerful tool to study enumerative problems is given by Gromov—Witten invariants. These are supposed to give answers to enumerative problems, but in this talk, I will show that this expectation is actually wrong. I will instead introduce “reduced” invariants from cuspidal curves, which are more enumerative, and I will discuss a relation between standard and reduced Gromov—Witten invariants. This talk is part of the Geometry and Mathematical Physics seminar series. ## This talk is included in these lists:- Bham Talks
