Hermitian and Kähler submanifolds of a quaternionic Kähler manifold

open access: yes, 2001
Let \((M^{2m}, g)\) be a submanifold of a quaternionic Kähler manifold \((\widetilde{M}^{4n},Q,\widetilde{g})\) with induced metric \(g=\widetilde{g}_{|M}\) and \(J\) a \(g\)-orthogonal almost complex structure on \(M^{2m}\). The manifold \((M^{2m},J,g)\) is called an almost Hermitian submanifold of \(\widetilde{M}\) if there is a section \(J_1:M ...

Isospectral nearly Kaehler manifolds

open access: yes, 2017
We give an Ansatz to construct pairs of locally homogeneous nearly Kaehler manifolds that are isospectral for the Dirac and the Hodge Laplace operator in dimensions higher than six and investigate the existence of generic isospectral pairs in dimension six.
