Özgür Boyacıoğlu Kalkan, Rafael López

摘要:

在这项工作中,我们考虑类空曲面在Minkowski空间$\hbox{\bf E}%_{1}^{3}$满足线性Weingarten条件的类型$κ_{1}=mκ_{2}+n$,其中$m$和$n$是常数和$κ_{1}$和$κ_{2}$表示的主曲率在每个点的表面。研究了平行平面上由单参数圆族所分割的曲面族。我们证明了表面必须是旋转的或表面的一部分,家庭的黎曼极大曲面的例子($m=-1$,$n=0$)。最后,我们考虑的情况下,$n=0$的旋转曲面类,获得第一个积分,如果轴是类时和类空和一个完整的描述,如果轴是类光。

英文摘要:

In this work, we consider spacelike surfaces in Minkowski space $\hbox{\bf E}%_{1}^{3}$ that satisfy a linear Weingarten condition of type $κ_{1}=mκ_{2}+n$, where $m$ and $n$ are constant and $κ_{1}$ and $κ_{2}$ denote the principal curvatures at each point of the surface. We study the family of surfaces foliated by a uniparametric family of circles in parallel planes. We prove that the surface must be rotational or the surface is part of the family of Riemann examples of maximal surfaces ($m=-1$, $n=0$). Finally, we consider the class of rotational surfaces for the case $n=0$, obtaining a first integration if the axis is timelike and spacelike and a complete description if the axis is lightlike.
