Stability and Existence of Surfaces in Symplectic 4-Manifolds with $b^{+}=1$

Abstract

We establish various stability results for symplectic surfaces in symplectic $4-$manifolds with $b^{+}=1$. These results are then applied to prove the existence of representatives of Lagrangian ADE-configurations as well as to classify negative symplectic spheres in symplectic $4-$manifolds with $\kappa =-\infty$. This involves the explicit construction of spheres in rational manifolds via a new construction technique called the tilted transport.

Comments welcome!
