Report

Topological complexity of enumerative problems and classifying spaces of $PU_n$

Autor: Chen, Weiyan, Gu, Xing

We study the topological complexity, in the sense of Smale, of three enumerative problems in algebraic geometry: finding the 27 lines on cubic surfaces, the 28 bitangents and the 24 inflection points on quartic curves. In particular, we prove lower b

Topological complexity of finding flex points on cubic plane curves

Autor: Chen, Weiyan, Wan, Zheyan

We prove a lower bound for the topological complexity, in the sense of Smale, of the problem of finding a flex point on a cubic plane curve. The key is to bound the Schwarz genus of a cover associated to this problem. We also show that our lower boun

Choosing points on cubic plane curves: rigidity and flexibility

Autor: Banerjee, Ishan, Chen, Weiyan

Publikováno v: Advances in Mathematics, 418 (April 2023)

Every smooth cubic plane curve has 9 flex points and 27 sextatic points. We study the following question asked by Farb: Is it true that the known algebraic structures give all the possible ways to continuously choose $n$ distinct points on every smoo
