Sasakian空间型中双调和子流形的显式公式

Explicit formulas for biharmonic submanifolds in Sasakian space forms

D. Fetcu, C. Oniciuc

摘要:

对Sasakian空间型中的双调和Legendre曲线进行了分类,得到了它们在具有Tanno定义的正则和变形Sasakian结构的$(2n+1)$维单位球面中的显式参数方程.然后,结合Reeb向量场的流,将双调和积分子流形变换为双调和反不变子流形。使用这种方法,我们得到新的例子,双调和子流形领域,特别是在$\mathbb{S}^{7}$。

英文摘要:

We classify the biharmonic Legendre curves in a Sasakian space form, and obtain their explicit parametric equations in the $(2n+1)$-dimensional unit sphere endowed with the canonical and deformed Sasakian structures defined by Tanno. Then, composing with the flow of the Reeb vector field, we transform a biharmonic integral submanifold into a biharmonic anti-invariant submanifold. Using this method we obtain new examples of biharmonic submanifolds in spheres and, in particular, in $\mathbb{S}^{7}$.
