Dissolving four-manifolds and positive scalar curvature
B. Hanke, D. Kotschick, J. Wehrheim
We prove that many simply connected symplectic four-manifolds dissolve after connected sum with only one copy of . For any finite group G that acts freely on the…

Signatures of foliated surface bundles and the symplectomorphism groups of surfaces
D. Kotschick, S. Morita
For any closed oriented surface F of genus at least three, we prove the existence of foliated F-bundles over surfaces such that the signatures of the total spaces are non-zero. We…
