积空间中的常角曲面

Constant Angle Surfaces in Product Spaces

Franki Dillen, Daniel Kowalczyk

摘要:

我们对$M^2(c_1)\times M^2(c_2)$中的所有曲面进行分类,对于这些曲面,切空间$T_pM^2$与$T_p(M^2(c_1)\times \{p_2\})$(或等价地,对于$M^2$的每个点$p=(p_1,p_2)$,与$T_p(\{p_1\}\times M^2(c_2))$)成恒定角度。这里$M^2(c_1)$和$M^2(c_2)$是二维空间形式,不是都是平面的。作为推论,我们给出了$M^2(c_1)\times M^2(c_2)$中所有全测地曲面的分类。

英文摘要:

We classify all the surfaces in $M^2(c_1)\times M^2(c_2)$ for which the tangent space $T_pM^2$ makes constant angles with $T_p(M^2(c_1)\times \{p_2\})$ (or equivalently with $T_p(\{p_1\}\times M^2(c_2))$ for every point $p=(p_1,p_2)$ of $M^2$. Here $M^2(c_1)$ and $M^2(c_2)$ are 2-dimensional space forms, not both flat. As a corollary we give a classification of all the totally geodesic surfaces in $M^2(c_1)\times M^2(c_2)$.
