It makes sense to talk about k(P), a k-valued skyscraper sheaf supported at P, only when we're thinking about k(P) as a sheaf of rings, like when we're thinking of it as the structure sheaf of P.

WebAug 27, 2024 · Let y be any solution of Equation 2.3.12. Because of the initial condition y(0) = − 1 and the continuity of y, there’s an open interval I that contains x0 = 0 on which y has no zeros, and is consequently of the form Equation 2.3.11. Setting x = 0 and y = − 1 in Equation 2.3.11 yields c = − 1, so. y = (x2 − 1)5 / 3. WebProve Theorem 3.12.2. This problem has been solved!
