Nov 19, 2022 at 14:08 comment added Scott Armstrong I think you can find $\xi$ by taking $\xi = \nabla u + \nabla^\perp v$ where $\Delta u = f$ and $\Delta v = g$. So your question reduces to Calderon-Zygmund on the sphere, for the Laplacian. I don't know a reference off the top of my head, but I suppose one should exist.

Nov 18, 2022 at 17:16 comment added Chris Sure, I'll add in these details. The source is Christodoulou and Klainerman's book on the Global Nonlinear Stability of Minkowski Space.
Nov 18, 2022 at 0:36 comment added Piotr Hajlasz Can you provide more details? page 43 of what? I would like to see the source it could help answer the questions. What are $f,g,\xi$? What is the dimension of the sphere etc. I do not want to guess. I might know how to answer the question, but I would like to see a more detailed statement.
