Title: Yamabe invariant of symplectic 4-manifolds of general type

Abstract: We compute the Yamabe invariant for a class of symplectic 4-manifolds obtained by
taking the rational blow-down of Kahler surfaces. In particular, for any point on the half-Noether
line we show that there is a minimal symplectic manifold with known Yamabe invariant.
