| Dec 6, 2023 at 4:26 | comment | added | Sardine | Thanks for the thorough answer, I'll need some time to digest it! Could you clarify why you mention an assumption that $\partial F$ is symmetric? The reason I introduced a matrix $M$ such that $\partial F = gM$ is that $\partial F$ is not symmetric. This may be a minor detail. I also didn't think to mention that $F$ is assumed injective over a domain (smooth, convex) $E$. | |
