WebOct 2, 2024 · If you only care about reduced schemes, this proof is easier and one avenue to show that $\Omega_{X/Y}$ is locally free of the correct rank is Hartshorne's exercise II.5.8(c), which states that a coherent sheaf on a reduced noetherian scheme with constant rank is locally free. WebA vector field can be thought as autonomous differential equation and I do not see clearly how to consider the sheaf of its solutions. On the other hand when we have a non-autonomous ordinary differential equation then there is its sheaf of solutions. This sheaf is a sheaf over the time variable only and not the whole space.
