In terms of the almost complex connection and the unitary moving frame,a complex version on the theory of the nearly Kaehler structure in S^6 is given.Under this framework, minimal surfaces in the nearly Kaehler,S^6 are studied.A complete classification for complete minimal surfaces in S^6 with constant,Kaehler angle and nonnegative curvature is given.Moreover,almost complex curves in S^6 are considered. 相似文献

In this article, we introduce a new method for manufacturing harmonic morphisms from semi-Riemannian manifolds. This is employed
to yield a variety of new examples from the compact Lie groups SO(n), SU(n) and Sp(n) equipped with their standard Riemannian metrics. We develop a duality principle and show how this can be used to construct
the first known examples of harmonic morphisms from the non-compact Lie groups , SU
*(2n), , SO
*(2n), SO(p, q), SU(p, q) and Sp(p, q) equipped with their standard dual semi-Riemannian metrics.

ABSTRACT We study the varieties of Lie algebra laws and their subvarieties of nilpotent Lie algebra laws. We classify all degenerations of (almost all) five-step and six-step nilpotent seven-dimensional complex Lie algebras. One of the main tools is the use of trivial and adjoint cohomology of these algebras. In addition, we give some new results on the varieties of complex Lie algebra laws in low dimension. 相似文献

Abstract The purpose of this paper is to extend the result in Park (Park, J. (2001). Birational maps of del Pezzo fibrations. J. Reine Angew. Math. 538:213–221) in the case of del Pezzo fibrations of degree 1. To this end we investigate the anticanonical linear systems of del Pezzo surfaces of degree 1. We then classify all possible effective anticanonical divisors on Gorenstein del Pezzo surfaces of degree 1 with canonical singularities. 相似文献
