Generators for the cohomology ring of the moduli of one-dimensional sheaves on $\mathbb{P}^2$ (2204.05866v2)

Abstract: We explore the structure of the cohomology ring of the moduli space of stable 1-dimensional sheaves on $\mathbb{P}^2$ of any degree. We obtain a minimal set of tautological generators, which implies an optimal generation result for both the cohomology and the Chow ring of the moduli space. Our approach is through a geometric study of tautological relations.
