A report on almost quaternionic Hermitian manifolds

1995
Let \(M^{4n}\) be a \(4n\)-dimensional manifold. An almost hypercomplex Hermitian structure on \(M^{4n}\) is defined by a pair \((H,g)\) on \(M^{4n}\), where \(H=(J_\alpha )_{\alpha =1,2,3}\) is an almost hypercomplex structure on \(M^{4n}\) and \(g\) is a Riemannian metric on \(M^{4n}\) which is Hermitian with respect to \(H\).

Spectral geometry for almost isospectral hermitian manifolds

Geometriae Dedicata, 1993
The author studies the relationship between the spectral geometry of a Riemannian manifold and its holomorphic geometry. Let \(\lambda_{n}^{p,q}\) be the eigenvalues of the complex Laplacian on forms of type \((p,q)\). One says two Hermitian manifolds are strongly \(\alpha\) isospectral if for all \((p,q)\) \[ sup_{n\rightarrow\infty}\mid\lambda_{n ...

Complex submanifolds in almost Hermitian manifolds

1987
A complex hypersurface M in an almost Hermitian manifold is called a \(\sigma\)-hypersurface if the second fundamental form \(\sigma\) and the almost complex structure J satisfy \(\sigma (X,JY)=\sigma (JX,Y)=J\sigma (X,Y)\) for X, Y tangent to M. The main purpose of this article is to obtain some equivalent conditions for a \(\sigma\)-hypersurface to ...
