Ruled 4-manifolds and isotopies of symplectic surfaces
R. Hind, A. Ivrii
Abstract
We study symplectic surfaces in ruled symplectic 4-manifolds which are disjoint from a given symplectic section. As a consequence we see that, in any symplectic 4-manifold, two homologous symplectic surfaces which are sufficiently C0 close must be Hamiltonian isotopic.
