An upper bound for a Hilbert polynomial on quaternionic Kahler manifolds
Uwe Semmelmann, Gregor Weingart
In this article we prove an upper bound for a Hilbert polynomial on quaternionic Kaehler manifolds of positive scalar curvature. As corollaries we obtain bounds on the quaternionic…
Conformal Killing forms on Riemannian manifolds
U. Semmelmann
Conformal Killing forms are a natural generalization of conformal vector fields on Riemannian manifolds. They are defined as sections in the kernel of a conformally invariant first…
Twistor Forms on Kaehler Manifolds
Andrei Moroianu, Uwe Semmelmann
Twistor forms are a natural generalization of conformal vector fields on Riemannian manifolds. They are defined as sections in the kernel of a conformally invariant first order dif…
Symmetries of Contact Metric Manifolds
Florin Belgun, Andrei Moroianu, Uwe Semmelmann
We study the Lie algebra of infinitesimal isometries on compact Sasakian and K--contact manifolds. On a Sasakian manifold which is not a space form or 3--Sasakian, every Killing ve…
