Algebraic Geometry


Second semester graduate algebraic geometry. This course will focus on algebraic curves and surfaces, especially over an algebraically closed field. Topics on curves will include Riemann-Roch, the Riemann-Hurwitz formula, embeddings in projective space, elliptic curves, Jacobians of curves, and related topics. The study of surfaces will include the adjunction and projection formulas, Riemann-Roch for surfaces, Noether's formula, Hodge Index Theorem, Nakai-Moishezon Criterion, ruled surfaces, monoidal transformations, and related topics. The course will also develop and use cohomology for schemes, both from the Cech and derived functor points of view, a key result being Serre Duality. Other types of cohomology in algebraic geometry will also be discussed.

Class schedule: Mon and Wed, 10:30-noon, on Zoom, from Jan. 20 to April 28, 2021. (No class on Fri., Feb. 12; Wed., March 10; Fri., March 12.)
