摘要：In this talk, we introduce a method to study the cohomology of the moduli space of one-dimensional sheaves on smooth projective surfaces. It mainly relies on the geometry of relative Abelian–Jacobi maps and the full support theorem of Maulik–Yun and Migliorini–Shende. Our result has applications to BPS numbers in enumerative geometry, as well as to the proof of an asymptotic version of the "P=C" conjecture by Kononov–Pi–Shen and Kononov–Lim–Moreira–Pi for the projective plane, which is a compact analogue of the famous "P=W" conjecture on the moduli space of Higgs bundles. The talk is based on a series of joint works with Feinuo Zhang, and also with Weite Pi, Junliang Shen, and Feinuo Zhang.
