DISSOLVING FOUR-MANIFOLDS AND POSITIVE SCALAR CURVATURE B. HANKE, D. KOTSCHICK, AND J. WEHRHEIM A BSTRACT. We prove that many simply connected symplectic fourmanifolds dissolve after connected sum with only one copy of S

POSITIVE SCALAR CURVATURE WITH SYMMETRY BERNHARD HANKE A BSTRACT. We show an equivariant bordism principle for constructing metrics of positive scalar curvature that are invariant under a given group action. Furthermore,
