WebRiemann-Hurwitz and Applications Adam B Block 4 August, 2024 1 Introduction The following is an important application of the theorem of Riemann and Roch. The Riemann-Hurwitz formula allows one to compare genera of nonsingular curves over algebraically closed elds and is used often in computations. WebDec 8, 2024 · Riemann-Roch theorem: dim H 0 ( X, D) − dim H 1 ( X, D) = 1 − g + deg ( D) Combining with Serre duality we have dim H 0 ( X, D) − dim H 0 ( X, K X − D) = 1 − g + deg ( D) where K X is the canonical divisor. We also know that g = H 1 ( X, O X) = H 0 ( X, Ω X 1). people30
