For an immersed Lagrangian submanifold, let $\check{A}$ be the Lagrangian trace-free second fundamental form. In this note we consider the equation $\nabla^*T=0$ on Lagrangian surfaces immersed in $\mathbb{C}^2$, where $T=-2\nabla^*(\check{A}\lrcorner\omega)$, and we prove a gap theorem for the Whitney sphere as a solution to this equation.

惠特尼球的能隙现象

对于浸入式拉格朗日子流形,令 $\check{A}$ 为拉格朗日无迹第二基本形式。在本笔记中,我们考虑浸入 $\mathbb{C}^2$ 的拉格朗日曲面上的方程 $\nabla^*T=0$,其中 $T=-2\nabla^*(\check{A}\lrcorner\ omega)$,我们证明了惠特尼球的间隙定理作为该方程的解。
