| Nov 28, 2017 at 10:33 | comment | added | Jason Starr | The failure of Proposition 2 in the symplectic geometry setting is a major issue with extending much of the "minimal model program" to the symplectic setting (Ruan's program). Specifically, for an elliptic differential operator between two smooth vector bundles on the 2-sphere, as arises from the $\overline{\partial}$-equation on a holomorphic vector bundle on $\mathbb{CP}^1$, even if the kernel of the differential operator surjects onto one fiber of the domain, this does not necessarily imply vanishing of the cokernel (vanishing of $H^1$, which then implies surjectivity for every fiber). | |
