四维Minkowski空间中的双曲或椭圆型Chen旋转曲面

Chen Rotational Surfaces of Hyperbolic or Elliptic Type in the Four-dimensional Minkowski Space

Georgi Ganchev, Velichka Milousheva

摘要:

本文研究四维Minkowski空间中的类空曲面类,该类曲面在任意点的中曲率向量为非零的类空向量或类时向量。这些曲面是由满足某些自然条件的八个不变函数确定的。Chen曲面的子类的特征在于这些不变量之一为零的条件。本文描述了所有双曲型或椭圆型Chen类空旋转曲面。

英文摘要:

We study the class of spacelike surfaces in the four-dimensional Minkowski space whose mean curvature vector at any point is a non-zero spacelike vector or timelike vector. These surfaces are determined up to a motion by eight invariant functions satisfying some natural conditions. The subclass of Chen surfaces is characterized by the condition one of these invariants to be zero. In the present paper we describe all Chen spacelike rotational surfaces of hyperbolic or elliptic type.
