Construction of G_2-instantons via twisted connected sums
Grégoire Menet, Johannes Nordström, Henrique N. Sá Earp
We propose a method to construct G_2-instantons over a compact twisted connected sum G_2-manifold, applying a gluing result of Sá Earp and Walpuski to instantons over a pair of 7-m…
Exotic G_2-manifolds
Diarmuid Crowley, Johannes Nordström
We exhibit the first examples of closed 7-dimensional Riemannian manifolds with holonomy G_2 that are homeomorphic but not diffeomorphic. These are also the first examples of close…
Asymptotically cylindrical Calabi-Yau 3-folds from weak Fano 3-folds
Alessio Corti, Mark Haskins, Johannes Nordström +1
We prove the existence of asymptotically cylindrical (ACyl) Calabi-Yau 3-folds starting with (almost) any deformation family of smooth weak Fano 3-folds. This allow us to exhibit h…
