Conformal foliations, Kähler twists and the Weinstein construction
Paul-Andi Nagy, Liviu Ornea
We classify both local and global Kähler structures admitting totally geodesic homothetic foliations with complex leaves. The main building blocks are related to Swann's twists an…

Second order Einstein deformations
Paul-Andi Nagy, Uwe Semmelmann
We study the integrability to second order of infinitesimal Einstein deformations on compact Riemannian and in particular on Kähler manifolds. We find a new way of expressing the…
