Symplectic Structures with Non-Isomorphic Primitive Cohomology on open 4-Manifolds

Matthew Gibson, Li-Sheng Tseng, Stefano Vidussi

We analyze four-dimensional symplectic manifolds of type $X=S^1\times M^3$ where $M^3$ is an open $3$-manifold admitting inequivalent fibrations leading to inequivalent symplectic…
