Asymptotically cylindrical Calabi-Yau manifolds
Mark Haskins, Hans-Joachim Hein, Johannes Nordström
Let be a complete Ricci-flat Kahler manifold with one end and assume that this end converges at an exponential rate to for some compact connected Ricci-fl…
New invariants of G_2-structures
Diarmuid Crowley, Johannes Nordström
We define a Z/48-valued homotopy invariant nu of a G_2-structure on the tangent bundle of a closed 7-manifold in terms of the signature and Euler characteristic of a coboundary wit…
G_2-manifolds and associative submanifolds via semi-Fano 3-folds
Alessio Corti, Mark Haskins, Johannes Nordström +1
We provide a significant extension of the twisted connected sum construction of G_2-manifolds, i.e. Riemannian 7-manifolds with holonomy group G_2, first developed by Kovalev; alon…
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…
