Structure of the module of derivations on the space of Holomorphic functions
If you have a smooth manifold $M$, then you have a linear map $\mathfrak{X}(M) \to \text{Der}(C^{\infty}(M))$ from the space of smooth global vector fields to the space of derivations of the algebra of … Here is a proof of a similar result for real-analytic manifolds (real-analytic vector fields are exactly derivations of the algebra of real-analytic functions) by David Speyer. …
