Hartshorne 1.3 solution
WebJun 23, 2024 · In the book Algebraic Geometry by Hartshorne, Example V.1.4.1 says C 2 = deg C ( L ( C) ⊗ O C) holds due to Lemma V.1.3. Here, C is a nonsingular curve on a nonsingular projective surface X. The statement of Lemma V.1.3 is Lemma 1.3. Let C be an irreducible nonsingular curve on X, and let D be any curve meeting C transversally. Then

Now the problem only demands that we want a rational function regular everywhere except at Pbut it does not specify the order. Thus consider D= nP. We want l(nP) >1 so that we get a nonconstant rational function which ... probiotics shoppersWebProblem I.3.20 in Hartshorne asks to show that if Y is a variety such that dim Y ≥ 2 and Y is normal at a point P, then any regular function on Y − P extends to a regular function on Y.
