在本文中,我们研究了S13中的一个广泛的类空曲面族,其中包括,例如,常平均曲率为1的曲面和平坦曲面:那些平均曲率和Gauss-Kronecker曲率证明线性关系2a(H−1)+B(K−1)=0的曲面,其中a,B∈R,a+B≠0。我们表明,这些表面可以参数化的全纯数据,我们用它来分类完整的表面从这个家庭与非负高斯曲率。
In this paper we study a wide family of spacelike surfaces in S13which includes, for instance, constant mean curvature 1 surfaces and flat surfaces: those whose mean and Gauss–Kronecker curvatures verify the lineal relationship 2a(H−1)+b(K−1)=0 for a,b∈R,a+b≠0. We show that these surfaces can be parametrized with holomorphic data and we use it to classify the complete surfaces from this family with non-negative Gaussian curvature.
