| Dec 1, 2015 at 7:07 | comment | added | Ali Taghavi | @FanZheng If $M$ is a surface in $\mathbb{R}^{3}$ with Gauss normal vector $N$, the shape operator at each point $p\in M$ is a linear map $S$ on the tangent space $T_{p} M$ with $S(X)=\nabla_{X}^{N}$. Example: this operator is the identity operator for the round sphere. | |
