Algebra Seminar Speaker: Dawei Chen, Boston College Title: Moduli of subcanonical points Abstract: Subcanonical points are special Weierstrass points on smooth algebraic curves whose semigroups are symmetric. In this talk, I will explain the rich geometry of the moduli space of subcanonical points, with a focus on its connected components, birational geometry, topology, and the deformation theory […]

Algebra Seminar Speaker: Matt Broe, Boston University Title: The Beilinson-Bloch conjecture for some non-isotrivial varieties over global function fields Abstract: The Beilinson-Bloch conjecture is a generalization of the Birch and Swinnerton-Dyer conjecture, which relates the ranks of Chow groups of smooth projective varieties over global fields to the order of vanishing of L-functions. We prove […]
