Renato G. Bettiol, Paolo Piccione

摘要:

经典Delaunay曲面是空间型的高对称常中曲率(CMC)子流形。利用上齐性群作用几何学和变分分歧技巧,证明了一类紧致流形中Delaunay型超曲面的存在性.我们的建设专门为经典的例子,在圆形领域,并允许获得Delaunay型超曲面在许多其他环境空间,从复杂的和四元数的射影空间的Kervaire奇异球。

英文摘要:

Classical Delaunay surfaces are highly symmetric constant mean curvature (CMC) submanifolds of space forms. We prove the existence of Delaunay-type hypersurfaces in a large class of compact manifolds, using the geometry of cohomogeneity one group actions and variational bifurcation techniques. Our construction specializes to the classical examples in round spheres, and allows to obtain Delaunay-type hypersurfaces in many other ambient spaces, ranging from complex and quaternionic projective spaces to Kervaire exotic spheres.
