A rigidity theorem for quaternionic Kähler structures

Research output: Contribution to journalArticle

Abstract

We study the moduli space of quaternionic Kähler structures on a compact manifold of dimension 4n < 12 from a point of view of Riemannian geometry, rather than that of twistor theory. Then we obtain a rigidity theorem for quaternionic Kähler structures of nonzero scalar curvature by observing the moduli space.
