The almost Schur Lemma in quaternionic contact geometry

چکیده
We establish quaternionic contact (qc) versions of the so called Almost Schur Lemma, which give estimations qc scalar curvature on a compact manifold to be constant in terms norm $$[-1]$$ -component and trace-free part [3]-component horizontal Ricci tensor torsion endomorphism, under certain positivity conditions.

Fano Manifolds, Contact Structures, and Quaternionic Geometry
Let Z be a compact complex (2n+1)-manifold which carries a complex contact structure, meaning a codimension-1 holomorphic sub-bundle D ⊂ TZ which is maximally non-integrable. If Z admits a Kähler-Einstein metric of positive scalar curvature, we show that it is the Salamon twistor space of a quaternion-Kähler manifold (M, g). If Z also admits a second complex contact structure D̃ 6= D, then Z = C...
متن کاملAbout the geometry of almost para-quaternionic manifolds
We provide a general criteria for the integrability of the almost para-quaternionic structure of an almost para-quaternionic manifold (M,P) of dimension 4m ≥ 8 in terms of the integrability of two or three sections of the defining rank three vector bundle P. We relate it with the integrability of the canonical almost complex structure of the twistor space and with the integrability of the canon...
متن کاملThe differential geometry of almost Hermitian almost contact metric submersions
Three types of Riemannian submersions whose total space is an almost Hermitian almost contact metric manifold are studied. The study is focused on fundamental properties and the transference of structures. 1. Introduction. In this paper, we discuss some geometric properties of Riemannian submersions whose total space is an almost Hermitian almost contact metric manifold. If the base space is an...
متن کاملQuaternionic Contact Einstein Structures and the Quaternionic Contact Yamabe Problem
A partial solution of the quaternionic contact Yamabe problem on the quaternionic sphere is given. It is shown that the torsion of the Biquard connection vanishes exactly when the trace-free part of the horizontal Ricci tensor of the Biquard connection is zero and this occurs precisely on 3-Sasakian manifolds. All conformal deformations sending the standard flat torsion-free quaternionic contac...
متن کاملalmost-quaternionic Hermitian manifolds
In this note we prove that if the fundamental 4-form of an almost-quaternionic Hermitian manifold (M,Q, g) of dimension 4n ≥ 8 satisfies the conformal-Killing equation, then (M,Q, g) is quaternionic-Kähler.
