摘要:
本文提出了一种结构策略,基于两个给定的极小子流形在球面中产生新的极小子流形。该方法是通过曲线 $γ\subset \mathbb S^3$ 以平衡的方式旋转给定的极小子流形,从而得到极小子流形——螺旋极小子积(spiral minimal products),它们构成了一个由 $C$ 和 $\tilde C$ 决定的、源于有趣钟摆现象的二维族。当 $C=0$ 时,我们将 [Bre13] 中解释的 $\mathbb S^3$ 中极小环面的构造推广到更高维的情形。当 $C=-1$ 时,我们重现了 [CLU06] 和 [HK12] 中关于球面中特殊勒让德子流形的先前相关工作,此外,还能在球面和复射影空间中分别获得大量 $\mathscr C$-全实和全实嵌入的极小子流形。本文的一个关键要素是应用 Harvey 和 Lawson [HL75] 关于极小子流形的优美扩展结果,以在我们的情形下建立旋转反射原理,从而确立曲线 $γ$。
英文摘要:
This paper exhibits a structural strategy to produce new minimal submanifolds in spheres based on two given ones. The method is to spin the given minimal submanifolds by a curve $γ\subset \mathbb S^3$ in a balanced way and leads to resulting minimal submanifolds $-$ spiral minimal products, which form a two-dimensional family arising from intriguing pendulum phenomena decided by $C$ and $\tilde C$. With $C=0$, we generalize the construction of minimal tori in $\mathbb S^3$ explained in [Bre13] to higher dimensional situations. When $C=-1$, we recapture previous relative work in [CLU06] and [HK12] for special Legendrian submanifolds in spheres, and moreover, can gain numerous $\mathscr C$-totally real and totally real embedded minimal submanifolds in spheres and in complex projective spaces respectively. A key ingredient of the paper is to apply a beautiful extension result of minimal submanifolds by Harvey and Lawson [HL75] for a rotational reflection principle in our situation to establish curve $γ$.
